Abstract

PURPOSE:To readily obtain a peptide antibody in a large amount at a low cost by preparing the peptide antibody from eggs produced by a chicken preingesting an antigen and providing the peptide antibody rapidly responsive to an undenatured peptide and affording the maximum antibody value in a short time. CONSTITUTION:Leucine enkephalin which is one kind of neuropeptide as an immunogen for a chicken is synthesized by a solid-phase synthetic method, then mixed with a polvinylpyrrolidone-phosphoric acid-buffered physiological saline solution and a complete Freund's adjuvant and emulsified to provide an antigenic liquid, which is subsequently subcutaneously injected into the thigh of the chicken to immunize the chicken. After immunization for the first time, immunizing operation is carried out three times at an interval of 2 weeks. The egg yolk of collected eggs is separated for 9 weeks after the initial immunization and the phosphoric acid buffered-physiological saline solution in an amount equal to that of the egg yolk is added thereto. A 0.1% sodium alginate solution is further added and centrifugation is performed to measure the specific antibody value of the resultant supernatant. An antibody is then collected from a water-soluble fraction in which the antibody value is raised in about the 7th week. Thereby, a large amount of the objective peptide antibody is readily obtained from the eggs produced by the chicken preingesting the antigen at a low cost.

However, in order to obtain the antibody, it was difficult to obtain the antibody even if the native peptide was used as it was for immunization as an antigen. For example, leucine enkephalin, which has 5 amino acids, has low immunogenicity as it is (A.CUPO, J.VION-DURY, Neuropeptid
es 8, p207-219, 1986). It is considered that the cause of this is that the peptide is decomposed by digestive enzymes in the living body and is not recognized as an antigen unless it has not only the antigenic determinant but also the carrier determinant.

Therefore, as a method for producing a peptide antibody,
As disclosed in JP-A-62-102157, a carrier protein having a large molecular weight which serves as a carrier moiety is bound to a peptide serving as an antigen to impart immunogenicity, and the antigen-carrier protein complex is bound to a mouse, a rabbit, It is known to immunize animals such as rats and prepare antibodies from the blood.

However, in such a method for producing a peptide antibody, since a carrier protein is used, not only an antibody against an antigen but also an antibody against the carrier protein is induced and, as a result, the antigen-antibody There was a risk that the affinity would be low. Furthermore, when the antigen is of mammalian origin, even when immunizing animals such as syngeneic mice, rabbits, and rats, when a low-molecular antigen such as a short-chain peptide is used, the antigen is not recognized, There was also the drawback that antibodies were difficult to produce.

In the method for producing a peptide antibody according to the present invention, the peptide antibody is obtained from the yolk of an egg produced by a chicken which has been previously ingested with the peptide as an antigen. In general, when the antigen is derived from a mammal, even when immunizing animals such as syngeneic mice, rabbits and rats, when a low molecular antigen such as a short chain peptide is used, the antigen is not recognized and the antibody Was hard to produce. As a result of diligent studies by the present inventor, it was found that the chicken immune system also recognizes low molecular weight antigens such as peptides.

In the present invention, a short-chain peptide is used in consideration of the specificity of the produced antibody. Specifically, a peptide having 2 to 50 amino acids, preferably 3 amino acids
One or more and 15 or less short-chain peptides are used. This is because the peptide site that serves as an antigenic determinant in vivo consists of several amino acids.

(4) Method for measuring antibody titer Leucine enkephalin used as an antigen was prepared in a PBS solution so as to have a concentration of 50 μg / ml, and 100 μl was added to each well of a 96-well microtiter plate (manufactured by Nippon Intermed). Dispensed. 2 hours at 37 ℃, 4 ℃
And reacted overnight at. Then, after washing 3 times with PBS, block Ace (Dainippon Pharmaceutical Co., Ltd.) is ¼ PBS
300 μl of the solution diluted with was dispensed into each well of the plate. After reacting at 37 ° C. for 1 hour, the plate was washed 3 times with PBS. The water-soluble fraction shown in (2) was diluted 1000 times with 1/10 Block Ace and dispensed in 100 μl portions. 37
After reacting for 2 hours at ℃, PBS-Tween (O.O.
It was washed 5 times with 1M phosphate buffered saline, pH 7.4 with Tween 20 added to bring the concentration to 0.05%).
As a secondary antibody, peroxidase-labeled rabbit anti-chicken IgG (manufactured by Cappel) was diluted 1000-fold with 1/10 Block Ace and dispensed in 100 μl aliquots at 37 ° C.
And reacted for 1 hour. After that, 5 with PBS-Tween
After washing twice, 3 mg of TMBZ-HCl (3,3 ′, 5,5′-tetramethylbenzidine, dihydrochloride) was dissolved in 5 ml of 0.01N HCl (pH 2). 30%
Dissolve 40 μl of H 2 O 2 in 10 ml of water and add 1 ml of this.

and 1 were mixed. In addition to the above TMBZ-HCl solution 4.2
A mixture of 9 ml was dispensed in 100 μl portions. 37
After reacting at 20 ° C. for 20 minutes, 200 μl of 1N sulfuric acid was dispensed and the absorbance at 450 nm was measured. The protein content of the sample is measured in advance (Bio-Rad Pr
The specific activity as the absorbance per protein amount was calculated. Specific activity = (antibody titer absorbance of Example sample-blank) / protein amount of working sample (mg) Here, the blank is the absorbance of the well to which the antigen is not immobilized. Subtract to correct for apparent antibody titer increase due to nonspecific reaction. As is clear from Figure 1,
It can be seen that the antibody titer increased by immunization three times and the maximum antibody titer was obtained around the 7th week. For those with a small immunization dose, it takes time for the antibody titer to rise, but
An increase in antibody titer was obtained even at 50 μg.

(4) Method for measuring antibody titer The antibody titer was measured in the same manner as in (4) of Example 1 to calculate the specific activity. As shown in FIG. 2, it can be seen that the antibody titer increased by immunization three times and the maximum antibody titer was obtained around the 7th week. The antibody titer of 500 μg immunized is low, but it continues to rise.
