Definitions
- the present invention relates to a method for producing a thread of silk proteins and to a device which is suitable for carrying out the method. Moreover, the invention is directed to threads obtained therefrom and their use.
- Natural silk e.g. Spider silk is an exceptional material that has a very high tensile strength in combination with a high extensibility. Because of these properties has been trying for years to produce this material in larger quantities. Since it is not possible to use animals such as To employ spiders for this purpose, research has focused on the study of methods in which the starting material for the silk (e.g., spider silk proteins) is recombinantly recovered and then spun into a thread.
- the starting material for the silk e.g., spider silk proteins
- Authentic silk proteins (recombinant proteins obtained with the help of authentic silk gene sequences) and synthetic silk proteins (proteins based on synthetic genes whose primary sequence largely corresponds to the natural sequence) are used as raw material.
- the quality of an artificially made yarn is presumably determined by both the raw material used and the spinning process used.
- the artificial silk particles must be converted from a soluble form to an insoluble fibrillar form, the structure of which should be as close as possible to that of the authentic thread.
- the research group of Jelinski developed a micro-spinning apparatus that allowed the spinning of a few milligrams of silk protein into silk threads several meters long (Liivak et al., 1998).
- the starting material used was silk of the spider Nephila clavipes dissolved in hexafluoroisopropanol. The protein thus dissolved was injected through a spinneret into a precipitation bath of acetone.
- Another group developed a spinning method in which a methanol / water mixture was used as a precipitation bath.
- a synthetic silk protein and recombinant MaSpI of the spider Nephila clavipes could be spun into threads from a urea-containing solution.
- US 2003/0201560 relates to an apparatus for spinning filaments from protein solutions. It is stated that the device has a funnel-shaped section through which the protein solution or "dope" is passed, this passage at least partially consisting of a semipermeable and / or porous material.
- WO 2005/017237 relates inter alia to a device for assembling proteins.
- the device comprises a tubular passage whose walls are partially permeable or porous. This has the advantage of controlling pH, water content and ionic composition.
- WO 2004/057069 relates to a method and a device for producing objects, in particular also for spinning threads made of spider silk proteins. This method mainly relates to the sol-gel transition of the protein solution, which is achieved, for example, by the addition of potassium, preferably potassium fluoride.
- the device used to carry out the method has a "transition compartment", which may be semipermeable or porous.
- WO 2003/060099 is concerned with the production of spider silk fibers or biofilaments.
- an "extrusion unit" is described, through which the spider silk protein solution is passed,
- WO 2003/060099 is directed to the introduction of the filaments into a coagulation bath after contact with air.
- an object of the present invention to provide a method and apparatus for producing silk proteins which obviates the need for the precipitation bath and the addition of non-natural, chaotropic or lyotropic agents. It is a further object of the present invention to produce by a method and an apparatus stable silk yarns having mechanical properties which approximate or correspond to natural silk proteins.
- An additional object of the invention is the production of silk yarns in high yield, i. in an amount suitable for large-scale production.
- the previously used methods for spinning spider silk proteins are usually based on the injection of a protein solution into a precipitation bath, wherein for stabilizing the soluble state of the proteins in the spinning solution therein usually chaotropic, lyotropic substances or organic solvents are included.
- the process according to the invention is based exclusively on aqueous solutions without additions of unnatural, chaotropic or lyotropic agents.
- the proteins are presumably in a conformational state that corresponds to the natural state.
- the thread assembly is completed by pulling on the partially assembled high protein phase. From studies on chemical polymers it is known that the stretching of concentrated polymer solutions leads to an orientation of the individual polymer chains and thus an increased stability of a fiber formed therefrom. Therefore, it is to be presumed that the tensile-based spinning method used here is superior to the pressure-based methods.
- the spinning apparatus of the present invention allows high performance synthetic spun silk fibers to be used, which find their uses in many fields of engineering and industry. In addition to ballistic applications such as the development of bulletproof equipment, synthetic spider silk could also be used for parachutes, specialty ropes and nets, sporting goods, textiles, but also for lightweight aircraft components.
- the present invention relates to a method for producing a thread of silk proteins, comprising the following steps:
- the winning of the silk thread is preferably done by train.
- the silk proteins are characterized by proteins of natural or recombinant origin, i. Proteins, for example, of arachnids
- insects insects (Insecta) are derived.
- the origin of the proteins are the silk moth ⁇ Bombyx mori), the lacewing (Chrysoperla carnea), the spider
- the silk proteins used herein may be authentic, ie, represent the natural sequences, or may be synthetic, ie synthetic gene-based proteins whose primary sequence corresponds largely to the natural sequence.
- diffusion unit as used herein describes a storage medium that allows for diffusion of components therefrom and into it.
- the diffusion unit of the present invention is not the porous or semi-permeable membrane of the prior art through which a one-sided passage from
- the diffusion unit of the present invention may be referred to as a matrix in which, on the one hand, the potassium and phosphate ions necessary for the formation of protein rich and poor phases
- the protein-poor phase of the silk protein solution (not to be used for the thread assembly) is taken up.
- the spinning solution provided in a) contains at least 1% -50%, preferably 10% -40%, most preferably 10% -20% (w / v) of silk protein.
- Solution is found to be from 4.0-12.0, preferably from 6.5-8.5, and most preferably 8.0. This solution is also called a "dope.” "Dope" means one
- Liquid or solution which may include protein aggregates in addition to protein monomers, for example dimers, trimers and / or tetramers.
- This protein solution may contain, in addition to the solvents listed below, also additives such as e.g.
- the solution preferably comprises a polar solvent selected from water, alcohols and mixtures thereof.
- alcohols include methanol, ethanol, propanol, isopropanol or polyhydric alcohols such as glycerol or propylene glycol.
- the latter solvents can be used in addition to their solvent properties as a means for adjusting the viscosity and / or as a preservative.
- the step of obtaining the silk thread includes contacting the protein rich phase with a gas or a liquid.
- the gas will be an oxygen-containing gas, ie when, inter alia, an oxidation effect is desired.
- the gas may also be an inert gas such as nitrogen, argon, helium, etc. Also suitable are mixtures of these gases.
- contacting with liquids may also be considered, examples being methanol, ethanol, propanol, isopropanol, acetone, acetonitrile, preferably methanol.
- the diffusion unit of the present invention is formed in a particularly preferred embodiment of a gel material.
- the gel material used is preferably a hydrogel, in particular a hydrogel comprising polyacrylamide, cellulose derivatives, polyvinyl methyl ether (PVME), polystyrene polybutadiene (PS-PB), stearyl acrylate, polyethylene (PE), polystyrene (PS), Polyvinyl alcohol (PVA), polyacrylic acid, poly (N-vinylpyrrolidone) - (PVP), polyethylene terephthalate (PET), polyisopropyleneacrylamide, polyethersulfonic acid and / or silicone hydrogels.
- PVME polyvinyl methyl ether
- PS-PB polystyrene polybutadiene
- PVA Polyvinyl alcohol
- PVP polyacrylic acid
- PVP poly (N-vinylpyrrolidone) -
- PET polyethylene terephthalate
- the diffusion unit may be formed of a ceramic.
- the present invention relates to an apparatus for carrying out the method defined above, comprising:
- the diffusion unit having a channel for passing the solution surrounded by a composition containing potassium and phosphate ions, the solution coming into contact with the potassium and phosphate ions diffusing out of the diffusion unit so that the diffusion unit at the exit of its channel is in contact with the provides a silk protein rich and low-phase separated solution;
- the first device is designed as a syringe coupled to a controllable pump.
- a controller such as a microcontroller, controls the controllable pump.
- the control device further comprises a memory in which a sequence program for the control of the controllable pump can be stored.
- the first device is designed as a controllable pumping system, which spends the solution in a continuous process in the Diffiisionsaku.
- the control program described above is designed such that it controls and thus ensures the continuous process for the introduction of the solution into the diffusion unit.
