Produktdetails

Produktmerkmale: The pre-B cell receptor (pre-BCR) expressed during the early stages of B lymphocyte development is a heterodimer of immunoglobulin heavy chain (IgH) with surrogate light chain, which is an Ig-light-chain-like molecule composed of the non-covalently linked Lambda 5 (λ5) and VpreB proteins. The pre-BCR is believed to control IgH repertoire selection and proliferation of differentiating B lymphocytes. The SL156 antibody reacts with a conformational epitope of the pre-BCR in transfected X63-Ag8.653 cells but not with surrogate light chain, λ5, or VpreB in the absence of IgH. It detects pre-BCR on pre-B cell lines, but not on pro-B cell lines or IgM-positive splenocytes. It also detects pre-BCR on the surface of pre-B cells, but not on Ig light chain (IgL)-positive B lymphocytes, from the bone marrow of normal mice. It has been noted that the cell-surface expression of pre-BCR is upregulated after a one-hour incubation of bone-marrow leukocytes in tissue culture medium at 37 °C. After immunization, cell-surface pre-BCR is detected on a subset of splenic IgL+ germinal-center B lymphocytes. Two-color analysis of Pre-B cell receptor (Pre-BCR) expression on bone-marrow pre-B lymphocytes. After immunomagnetic depletion of IgM+ cells using biotinylated anti-mouse IgM[b] mAb AF6-78 (Cat. No. 553519), C57BL/6 bone-marrow leukocytes were incubated for 1 hour in DMEM at 37 °C to enhance Pre-BCR expression. Then the leukocytes were stained with either biotinylated rat IgG2a, κ isotype control mAb R35-95 (Cat. No. 553928, left panel) or biotinylated mAb SL156 (right panel) in the presence of Mouse BD Fc Block™ purified anti-mouse CD16/CD32 mAb 2.4G2 (Cat. No. 553141/553142), followed by Streptavidin-APC (Cat. No. 554067) and FITC-conjugated anti-mouse CD45R/B220 mAb (Cat. No. 553087/553088). Flow cytometry was performed on a BD FACSCalibur™ flow cytometry system.
