Description

Description: This SPRCL5 monoclonal antibody reacts with Mouse CD185. CD185, which is also known as C-X-C chemokine receptor 5 (CXCR5) and Burkitt lymphoma receptor 1 (BLR1), is a seven transmembrane G protein-coupled receptor originally identified in Burkitt's lymphoma. In peripheral blood, CXCR5 is expressed on B cells, CD4+ T cells (but not Th1 or Th2 cells), as well as on a subpopulation of memory (CD45RO+) T cells. CXCR5+ circulating T cells are in a resting state and migrate to the lymph nodes due to expression of CCR7 and CD62L. In tonsil, CXCR5 is expressed on nearly all CD4+ cells along with CD45RO and such activation markers as CD69 and ICOS. Tonsillar CXCR5+ cells have been shown to induce antibody production when co-cultured with B cells, thus supporting their role in providing B cell help. Furthermore, this chemokine receptor plays a critical role in lymphocyte trafficking, in particular T cell migration into the B cell follicles of germinal centers in response to CXCL13, making CXCR5 an established marker of follicular helper T cells. This SPRCL5 does not see a formaldehyde fixed epitope, therefore staining should be done prior to fixation. Applications Reported: This SPRCL5 antibody has been reported for use in flow cytometric analysis. Applications Tested: This SPRCL5 antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 1 μg per test.

CXCR5 (C-X-Chemokine Receptor Type 5, CD185) also known as Burkitt lymphoma receptor 1 (BLR1) belongs to the CXC chemokine receptor family. CXCR5 is a G protein-coupled seven transmembrane receptor for chemokine BLC. CXCR5 gene is specifically expressed in Burkitt's lymphoma and lymphatic tissues, such as follicles in lymph nodes, as well as in spleen. Studies of CXCR5 suggest that it plays an essential role in B cell migration. CXCR5 expression has been reported in human blood and salivary gland and in animal lymphatic organs, blood, bone marrow, brain, liver, lymph node, skin, spleen, stomach, and tonsil. ESTs (expressed sequence tags) have been isolated from human brain, germ cell, lung, lymph, and pancreas. G-protein Coupled Receptors (GPCRs) comprise one of the largest families of signaling molecules with more than a thousand members currently predicted to exist. All GPCRs share a structural motif consisting of seven membrane-spanning helices, and exist in both active and inactive forms. An array of activating ligands participate in the conformation of GPCRs which leads to signaling via G-proteins and downstream effectors. Research studies have also shown the vast series of reactions which participate in the negative regulation of GPCRs. This "e;turn-off"e; activity in GPCRs have tremendous implications for the physiological action of the cell, and continues to drive pharmacological research for new drug candidates. Two blockbuster drugs which have been developed as GPCR-targeted pharmaceuticals are Zyprexa (Eli Lilly) and Claritin (Schering-Plough) which are used in mental health and allergy applications, respectively.
