Recombinant HIV-1 gp41,gp120

Inhibition of HIV Infection by Lectin Binding to gp120

Human immunodeficiency virus (HIV) is the causative agent of AIDS (acquired immunodeficiency syndrome). The polypeptide precursor gp160 of HIV-1 forms the external glycoprotein, gp120 and the transmembrane glycoprotein, gp41 (1 ). Sequence

Virion Attachment and Entry: HIV gp120 Env Biotinylation, gp120 Env, or Integrin Ligand-Binding Assay

2+ ) (Leitinger et al., Leitinger Biochim Biophys Acta 1498:91–98, 2000). Here we describe a protocol to detect biotinylated recombinant HIV-1 gp120 binding to integrin α4 β7 in both primary cells and cell lines expressing the gut-homing receptor.

【求助】HIV-gp41原核表达

秦奋 为什么HIV-gp41与原核PET28a质粒构建后，行诱导表达，SDS-PAGE无结果，而WB却有结果，这种情况怎么回事？（构建后测序同源性达95%，而且已酶切认证构建成功） 谢谢 zhujoker “SDS-PAGE无结果，而WB却有结果”是什么意思，你表述清楚一点，要不人家会有疑惑的。其实这主要看你是否诱导成功。个人认为还有就是你在原核里面表达，作为包涵体存在形式，你是否将蛋白提出来了呢？
