봉독의 항독소(IgY)생산을 위한 실험적 연구 = An Experimental Study on Production of Egg Yolk Antibody(IgY) against Bee Venom

다국어 초록 (Multilingual Abstract)

This study was carried out for production of neutral antibody to bee venom $(anti-phospholipase\;A_2IgY)$. Hen layings were injected repeatedly with bee venom and phospholipase $A_2$ with Freund's adjuvant. Specific antibody in egg yolk from immunized hen laying was separated, and purified, also immunological characteristics of anti phospholipase $A_2\;IgY$ was invested. The results were summarized as follows: 1. Phospholipase $A_2$ was showed single band at molecular weight 17,000 in SDS-PAGE and bee venom was showed two band at molecular weight 17,000 and under molecular weight 6,500 in SDS-PAGE. 2. During 70 days after hen immunized with bee venom and phospholipase $A_2$, antibodies(anti-bee venom IgY) to bee venom were showed poor ELISA value in egg yolk, but antibodies$(anti-Phospholipase\;A_2IgY)$ to phospholipase $A_2$ in egg yolk were increased ELISA value from 8 days or 15 days and found maximum ELISA value at 42 days. Also after booster at 49 days, ELISA value of anti Phospholipase $A_2\;IgY$ in egg yolk was supported at optical density(O.D) 1.0 level, continuously. 3. Titer of phospholipase $A_2\;IgY$ was showed 1: 32,000. 4. In double immunodiffusion test to phospholipase $A_2$ after double dilution of anti-phospholipase $A_2\;IgY$, only precipitation line was made in 1:1 dilution well of anti-Phospholipase $A_2\;IgY$. But In immunodiffusion test to anti-phospholipase $A_2\;IgY$ after double dilution of phospholipase $A_2$, Precipitation line to 250ul/ml well of phospholipase $A_2$ was showed. In double immunodiffusion test to bee venom(1mg/ml) after double dilution anti-phospholipase $A_2\;IgY$, all well without 1:32 dilution well were showed strong precipitation line. 5. In dot bloting test to anti-phospholipase $A_2\;IgY$ after diluting bee venom(0.5mg/ml), dot bloting color was showed clearly to $1/100(5{\mu}g/ml)$ in bee venom.
