Description :The 1B4C3 monclonal antibody recognizes human erbB3/HER3 also know as oncogene erbB3,tyrosine kinase cell surface receptor HER3, and C-erbB3. erbB3/HER3 is a receptor tyrosinekinase and a member of the epidermal growth factor receptor family. erbB3/HER3 binds theheregulin ligands and contains 4 furin-like repeats, 2 cheY receiver domains, and a tyrosinekinase domain with a predicted molecular weight approximately 148 kD. Signaling through theerbB3/HER3 receptor induces proliferation and differentiation in some cell types, the receptoris widely expressed in many tissues including kidney, lung, brain, placenta, skin and stomach.erbB3/HER3 forms constitutively active heterodimers with erbB2/HER2 in a subset of humanmammary tumors; expression of erbB3/HER3 reported be linked to favorable outcome inbladder and ovarian cancer. erbB3/HER3 has been shown to interact with a number of proteinsincluding EGF receptor, erbB2/HER2, erbB4, Grb2, Grb7, SOS1, cdk5, SHC, FAK, PTK6, andothers. The erb3/HER3 receptor is extensively phosphorylated at residues T873 and S1123(by cdk5); Y1199, Y1262, Y1289, and Y1328. The 1B4C3 antibody has been shown to beuseful for flow cytometric detection of human erbB3/HER3.

生物素亲和素(又称抗生物素)系统(biotin avidin system,BAS)标记抗体的技术是 20 世纪 70 年代后期发展起来的一种新的免疫检测方法。 由于亲和素与生物素间的亲和力极强,结合迅速,且极其稳定,生物素标记抗体和酶的标记率高,又不影响蛋白的活性,使 BAS 标记技术比常规酶联免疫、放射免疫及荧光免疫技术有着更高的灵敏度,为微量抗原、抗体的检测开辟了新的途径。近年来,在 BAS 检测中多用链霉亲和素“streptavidin,SA”,它是链霉菌培养过程中的分泌物,完整的链霉
3. 用NHSB量过量也是不利的,抗原的结合位点可能因此被封闭,导致抗体失活。 4. 由于抗体的氨基不易接近可能造成生物素化不足,此时可加入去污剂如Triton X-100,Tween 20等。 5. 当游离ε-氨基(赖氨酸残基的氨基)存在于抗体的抗原结合位点时,或位于酶的催化位点时,生物素化会降低或损伤抗体蛋白的结合力或活性。此时,应试用其它交联方法。 6. 生物素还可能与不同的功能基团,如羰基、氨基、巯基、异咪唑基及苯酚基,也可与糖基共价结合。 7. 交联反应后,应充分透析
点。给动物饲以大量鸡蛋白所致的维生素H缺乏,就是由于卵白素和大量的维生素H结合所致。维生素H(以下统称生物素)是一种小分子的维生素,分子量为244,系转氨甲酰基化过程中的辅酶,它与卵白素之间有很强的亲合力,较之抗体对抗原的亲合力要高出100万倍,能够彼此牢固结合而不影响彼此的生物学活性。同时,生物素与卵白素都具有与其它示踪物质如荧光素、铁蛋白和过氧化酶等相结合的能力。免疫细胞化学工作者利用上述特性,建立了卵白素―生物素免疫染色系统。由于维生素H习惯上称为生物素,为便于理解,现在译名上统称卵白素为抗生物素
