产品介绍：The highly glycosylated 75-120 kD antigen CD34 is possibly an adhesion molecule with a putative role in early hematopoiesis by mediating the attachment of stem cells to the bone marrow extracellular matrix or directly to stromal cells. It could act as a scaffold for the attachment of lineage specific glycans, allowing stem cells to bind to lectins expressed by stromal cells or other marrow components. CD34 is thought to have a role in presenting carbohydrate ligands to selectins. The intracellular chain of the CD34 antigen is a site of phosphorylation by activated protein kinase C, suggesting a putative role in signal transduction. Two isoforms of CD34 have been reported to be generated by alternative splicing. CD34 is highly expressed on hematopoietic progenitors, as well as on endothelial cells, brain, and testis. Staining for CD34 has been used to measure angiogenesis, which reportedly predicts tumor recurrence.
Function:
Possible adhesion molecule with a role in early hematopoiesis by mediating the attachment of stem cells to the bone marrow extracellular matrix or directly to stromal cells. Could act as a scaffold for the attachment of lineage specific glycans, allowing stem cells to bind to lectins expressed by stromal cells or other marrow components. Presents carbohydrate ligands to selectins.
Subcellular Location:
Membrane; Single-pass type I membrane protein.
Tissue Specificity:
Selectively expressed on hematopoietic progenitor cells and the small vessel endothelium of a variety of tissues.
Post-translational modifications:
Highly glycosylated. Phosphorylated on serine residues by PKC.
Similarity:
Belongs to the CD34 family.

文献和实验相关专题 实验原理 凡能刺激机体产生抗体，并能与抗体发生特异性结合的物质称为抗原 。物质所具有的这种特性称为抗原性（Antigenicity）。当机体受抗原刺激后，在体液中出现的一种能与相应抗原发生反应的球蛋白，称免疫球蛋白（Immunoglobulin, Ig）。含有免疫球蛋白的血清称免疫血清。 医学上常见的抗原物质，种类很多，如病原微生物及其代谢产物（毒素），异种动物血清（各种抗毒素，免疫 血清
