CD202b (TIE2) Monoclonal Antibody (33.1), eBioscience™, Invitrogen™

Beschreibung

Description: This 33.1 monoclonal antibody reacts with human, mouse, rabbit, rat, pig, and zebrafish CD202b. Also known as Tie-2, this molecule is a member of the tyrosine kinase receptor family. CD202b is expressed on endothelial and a subset of hematopoietic cells and is believed to play a role in both angiogenesis and hematopoiesis during development of the mouse embryo. In fetal liver and adult bone marrow, Tie-2 is expressed by a subpopulation of hematopoietic progenitor cells characterized as Lineage markers-, c-Kit+, Sca1+ cells. Long-term multilineage repopulating cells were detected in Tie-2+, Lineage-, c-Kit+, Sca1+ cells but not in Tie-2-, Lineage-, c-Kit+, Sca1+ cells. Applications Reported: This 33.1 antibody has been reported for use in western blotting. Applications Tested: This 33.1 antibody has been tested by immunoblotting of reduced cell lysate prepared from the bEND3 cell line at less than or equal to 5 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 µm post-manufacturing filtered.

The TEK receptor tyrosine kinase is expressed almost exclusively in endothelial cells in mice, rats, and humans. This receptor possesses a unique extracellular domain containing 2 immunoglobulin-like loops separated by 3 epidermal growth factor-like repeats that are connected to 3 fibronectin type III-like repeats. The ligand for the receptor is angiopoietin-1. Defects in TEK are associated with inherited venous malformations; the TEK signaling pathway appears to be critical for endothelial cell-smooth muscle cell communication in venous morphogenesis. TEK is closely related to the TIE receptor tyrosine kinase.
