Western Blot: BST2 Antibody (2E2)BSA Free [NBP2-29621]

Western Blot: BST2 Antibody (2E2)BSA Free [NBP2-29621]

Western Blot: BST2 Antibody (2E2) [NBP2-29621] - Analysis of BST2 protein in (A) human heart lysate, (B) human ovary lysate and (C) partial recombinant BST2 protein with monoclonal BST2 antibody at a concentration of 1 ug/ml. In the tested human lysates, two distinct bands were observed which represents the glycosylated (lower bands) and the ubiquitinated (higher bands ) forms of BST2 protein.

Immunohistochemistry-Paraffin: BST2 Antibody (2E2) - BSA Free [NBP2-29621]

Immunohistochemistry-Paraffin: BST2 Antibody (2E2) [NBP2-29621] - Analysis of BST2 protein in a section of human endometrial carcinoma using 5 ug/ml concentration of BST2 antibody (clone 2E2). The carcinoma cells depicted distinct membrane-cytoplasmic BST2 positivity with more intense staining in the cellular membranes, whereas, weak staining was observed in tumor stroma.

Application Notes
The unprocessed form of BST2 protein is 180 amino acids long (161 amino acids in its cleaved BST) and its cleaved form undergoes further modifications namely disulfide bond formation, GPI-anchor/GPI-like-anchor binding, glycosylation, isopeptide bond formation, lipidation and Ubl conjugation. The predicted molecular weight of unmodified BST2 protein is ~17-18kDa, whereas the post-translationally modified protein has been documented to run at ~25-36kDa (glycosylated), 50-55 kDa (ubiquitinated) and 65-70 kDa (dimers) in WB assay. BST2 protein localize mainly to the cell membranes from where it shuttles to the trans-Golgi network, late endosome and the cytoplasm. In immuno-staining assays, BST2 may develop a membrane-cytoplasmic staining pattern. This antibody is CyTOF ready.

Background: BST-2/Tetherin

Bst2 was first identified as a novel terminal B-cell-restricted antigen termed HM1.24 that is expressed on certain bone marrow cells as well as other tissues. The surface expression of Bst2 on fibroblast cell lines facilitated the stromal cell-dependent growth of DW34, a pre-B-cell line, suggesting that this protein is involved in pre-B-cell growth. Later experiments also showed it to be upregulated in several myeloma cells. More recently, Bst2 was identified an inhibitor of retroviral release from human cells whose activity is antagonized by the HIV-1 accessory protein Vpu. While Bst2 caused retention of virions on cell surfaces or endocytosis into Bst2-positive compartments, its depletion abolished the viral requirement for Vpu for virus release. This activity may represent a potential therapeutic strategy for the treatment of HIV/AIDS.
