Description
Die Erfindung betrifft ein Vorrichtung zur Hybridisierung von Proben an Arrays biologischer Stoffe.The The invention relates to a device for hybridization of samples on arrays of biological substances.
Hybridisierungen von DNA-Proben auf Oligomer Arrays werden zum Nachweis bestimmter Sequenzen in der Proben-DNA durchgeführt. Ein möglicher Ansatz, „Sequencing by Hybridisation (SBH)", ermittelt dabei sogar die vollständige Sequenz der Proben-DNA oder zumindest große Teile davon. Allelspezifische Hybridisierungen werden jedoch auch ausgeführt, um bestimmte Veränderungen in der Proben-DNA, z. B. Punktmutationen, nachzuweisen. Die Proben-DNA liegt jedoch, da sie zumeist vorher mittels PCR amplifiziert wurde, in der Regel doppelsträngig vor, damit steht sie im wesentlichen einer Hybridisierung mit den Oligomeren nicht mehr zur Verfügung. Die vorliegende Erfindung beschreibt eine Vorrichtung, die zur effizienten Hybridisierung von Proben an Oligomer Arrays dient.hybridizations DNA samples on oligomer arrays are used to detect certain Sequences performed in the sample DNA. One possible approach, "sequencing by hybridization (SBH) ", determined even the complete one Sequence of the sample DNA or at least large parts thereof. allele-specific However, hybridizations are also performed to certain changes in the sample DNA, e.g. B. point mutations to prove. The sample DNA lies however, since it was mostly amplified before by PCR, usually double-stranded ago, it is essentially a hybridization with the Oligomers are no longer available. The present invention describes a device that is efficient for Hybridization of samples to oligomer arrays serves.
Hybridisierungskammern werden inzwischen von verschiedenen Firmen kommerziell angeboten, sind aber in der Regel nicht separat temperierbar. Hybridisierungskammern, auch für die Aufnahme von Objektträgern geeignet, werden so z. B. von der Firma GeneMachines, CA, USA und von der Firma Telechem vertrieben. Auch gibt es an den Rändern selbstklebende Folien, die durch das Aufkleben auf Objektträger Hybridisierungskammern bilden können. Diese werden z. B. von der Firma Grace Biolabs angeboten. Die Firma Genetic Solutions hat auch pneumatisch ansteuerbare und temperierbare Hybridisierungskammern im Angebot, bei denen die Hybridisierungseigenschaften durch die Bewegung der Hybridisierungsflüssigkeit verbessert sein sollen. Alle diese Vorrichtungen erfordern jedoch, daß die dop pelsträngige Proben-DNA vor der Hybridisierung entweder thermisch denaturiert wird, einer der Stränge selektiv zuvor abgetrennt wird (z. B. kann ein Primer in der PCR mit Biotin markiert sein und in einem nachfolgenden Schritt durch Bindung an Streptavidin selektiv ein Strang aus der Lösung entfernt werden) oder aber durch enzymatische Verfahren ein Strang im Überschuß erzeugt wird, damit die an den Oligomer Array zu hybridisierenden Abschnitte nicht von komplementären Strängen blockiert werden. Diese Verfahren stellen nicht nur einen zusätzlichen Schritt dar, sondern sie sind auch speziell im Falle des Biotins teuer und im Falle enzymatischer Reaktionen oftmals schlecht reproduzierbar. Sollen beide Stränge jedoch durch den Oligomer Array nachgewiesen werden, so kommt ohnehin nur die thermische Denaturierung in Frage. Das Problem dabei ist jedoch das sogenannte Reannealing, das heißt daß die komplementären Stränge nach dem Denaturieren wiederum miteinander hybridisieren, was schneller als eine Hybridisierung mit Oligomeren auf dem Array erfolgen kann. Dieses Problem wird auch durch einmalige Denaturierung nicht gelöst. Wird dagegen in der Kammer denaturiert, so werden bereits an den Oligomer Array hybridisierte DNA-Fragmente ebenfalls wieder abgelöst. Abhilfe schafft eine Anordnung, in der die Probe periodisch aus der Hybridisierungskammer gepumpt wird, um nach externem Denaturieren durch Aufheizen wieder zurückgepumpt zu werden. Eine externe Pumpe führt jedoch leicht zu einem aufwendigen und großen und damit auch teuren Aufbau.hybridization chambers are now commercially offered by various companies are but usually not separately tempered. Hybridization chambers also for the inclusion of slides suitable, such. From GeneMachines, CA, USA and sold by Telechem. There are also self-adhesive at the edges Slides produced by sticking to slides hybridization chambers can form. These are z. B. offered by the company Grace Biolabs. The Company Genetic Solutions also has pneumatically controllable and temperature controlled Hybridization chambers on offer, where the hybridization properties should be improved by the movement of the hybridization fluid. However, all of these devices require that the double-stranded sample DNA is either thermally denatured before hybridization, a the strands selective previously isolated (eg, a primer in the PCR with biotin be marked and in a subsequent step by binding to Streptavidin selectively a strand can be removed from the solution) or but by enzymatic process a strand is generated in excess, so that the the oligomer array to be hybridized sections not blocked by complementary strands become. These methods not only provide an additional But they are also special in the case of biotin expensive and in the case of enzymatic reactions often poorly reproducible. Should both strands, however are detected by the oligomer array, so comes only anyway the thermal denaturation in question. The problem is, however the so-called reannealing, that is, the complementary strands after Denaturing in turn hybridize with each other, which is faster can be done as a hybridization with oligomers on the array. This problem is not solved by a single denaturation. Becomes on the other hand denatured in the chamber, so are already attached to the oligomer array hybridized DNA fragments also detached again. remedy provides an arrangement in which the sample is periodically pumped out of the hybridization chamber is pumped back to after external denaturation by heating to become. An external pump leads but easy to a complex and large and therefore expensive construction.
