应用

鸡卵白蛋白 (257-264)用于在免疫研究中触发T细胞活性。[1]
(鸡)卵清蛋白(257-264)用于:
  • 使小鼠致敏,生成哮喘模型[2]
  • 刺激脾细胞[3]
  • 交叉提呈研究中的阳性对照品,治疗树突状细胞[4]

生化/生理作用

SIINFEKL是鸡卵白蛋白(OVA)的I型(Kb)-限制性肽链表位;鸡卵白蛋白片段处在在I型MHC分子,H-2Kb。
(鸡)卵清蛋白(257-264)是一种抗原肽,可触发免疫应答。[5]向妊娠小鼠注射卵清蛋白肽有助于纠正耳发育异常。[6]

    We describe a quantitative histochemical method for demonstration of five N-acetyl-glucosamine binding lectins in the syncytiotrophoblast of human term placenta. The method employs biotinylated lectins and alkaline phosphatase-conjugated avidin. The alkaline phosphatase activity is detected by using 5-bromo-4-chloro-indoxyl phosphate as
