Background: ULBP-3
ULBP-3 is a member of a family of cell-surface proteins that function as ligands for human NKG2D. ULBP-3 has also been described under the names RaeT1N (retinoic acid early transcript), NKG2DL3, and ALCAN-gamma. The name ULBP-3 derives from the original identification of three proteins, ULBP-1, -2, and -3, as ligands for the human cytomegalovirus glycoprotein UL16; they were designated UL16 binding proteins (ULBP). The gene for ULBP-3 resides in a cluster of ten related genes, six of which encode potentially functional glycoproteins. Amino acid sequence identity within this family ranges from 30‑60%. These proteins are distantly related to MHC class I proteins, but they possess only the alpha 1 and alpha 2 Ig-like domains, and they have no capacity to bind peptide or interact with beta 2‑microglobulin. Some family members, including ULBP-3, are anchored to the membrane via a GPI-linkage, whereas others have transmembrane domains. ULBP-3 and several other family members are known to bind to human NKG2D, an activating receptor expressed on NK cells, NKT cells, gamma δ T cells, and CD8+ alpha beta T cells. Engagement of NKG2D results in the activation of cytolytic activity and/or cytokine production by these effector cells. The ULBPs are expressed on some tumor cells and have been implicated in tumor surveillance (1‑7).

文献和实验随着蛋白组学的深入研究，抗体标记技术也被广泛用于医学病理学、免疫组织化学、分子生物学、生物制药等领域，但很多科研人员在选择多种标记的抗体时遇到困难，那么今天我们一起了解这四种常用的抗体标记方法，这些方法平时都用对了吗？ 什么是抗体标记？ 抗体标记是指将标记物（酶，荧光素，生物素等）共价连接到抗体上，与待检测物（如某些特定抗原）特异性反应形成多元复合物，并借助于仪器对试验结果直接镜检观察或进行自动化测定，以用于对抗原、抗体反应进行定性和定位研究或进行定性和定量测定。 荧
当FITC在碱性溶液中与抗体蛋白反应时，主要是蛋白质上赖氨酸的r氨基与荧光素的硫碳胺键(thiocarbmide)结合，形成FITC-蛋白质结合物，即荧光抗体或荧光结合物。一个IgG分子中有86个赖氨酸残基，一般最多能结合15～20个，一个IgG分子可结合2～8个分子的FITC，其反应式如下FITC-N=C=S + N-H2-蛋白质 → FITC-NS-C-N-H2-蛋白质常用Marsshall(1958)法标记荧光抗体，也可以根据条件采用Chadwick等标记法或Clark
