STORAGE AND STABILITY
Kell血型糖蛋白(KEL)重组蛋白Storage: Avoid repeated freeze/thaw cycles. Store at 2-8oC for one month. Aliquot and store at -80oC for 12 months.
Stability Test: The thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37oC for 48h, and no obvious degradation and precipitation were observed. (Referring from China Biological Products Standard, which was calculated by the Arrhenius equation.) The loss of this protein is less than 5% within the expiration date under appropriate storage condition.

41的融合蛋白。其构建了重组的单链Fv(Single chain,Fv,scFv)抗体片段，scFv由抗红细胞膜血型糖蛋白抗体重链可变区（Vh）和轻链可变区（V1）组成，其间由15个残基-（GGGGS）3-连接体相连，在轻链可变区末端有来自HIV-1 gp41表面糖蛋白C末端八肽尾(FLAG)或-35肽。将此构建克隆入大肠杆菌表达载体pHFA，培养后，得到重组蛋白，即基因工程双功能试剂。在此基础上，建立了快速、灵敏和特异的自身红细胞凝集试验。基因工程抗体及其双功能试剂由于抗体分子小型化，因而具有较好
的血凝块的超薄切片中发现，Hp与“O”型RBC（后来证实按Lewis分型属Leb型”，及Hp与胃粘膜上皮细胞之间的关系，在高倍电镜下所见非常相似。这些特异的亲和现象很可能暗示着类似的粘附机制。1993年有人发现Hp特异地粘附于人胃粘膜上皮细胞受到人类初乳中SCIgA（一种携带高度多变的N－和O－连接的单糖链的糖蛋白）的抑制。当这种SC-IgA被墨角藻糖酶（α－L－fuco-sidase）降解后，抑制作用即降低，若用唾液酸（sialic acid）处理（曾有人报道Hp表达唾液酸特异的凝集素），并不
