CD43/Sialophorin Antibody (A2F8-R)

Western Blot: CD43/Sialophorin Antibody (A2F8-R) [NBP3-32154] - Western blot analysis of CD43/Sialophorin on different lysates with Mouse anti-CD43/Sialophorin antibody (NBP3-32154) at 1/1,000 dilution. Lane 1: K-562 cell lysate Lane 2: HL-60 cell lysate Lane 3: THP-1 cell lysate Lane 4: U-937 cell lysate Lane 5: HT-29 cell lysate (negative) Lysates/proteins at 20 ug/Lane. Predicted band size: 40 kDa Observed band size: 100-130 kDa Exposure time: 3 minutes; 4-20% SDS-PAGE gel. Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (NBP3-32154) at 1/1,000 dilution was used in 5% NFDM/TBST at 4C overnight. Goat Anti-Mouse IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.

Immunohistochemistry: CD43/Sialophorin Antibody (A2F8-R) [NBP3-32154] - Immunohistochemical analysis of paraffin-embedded human B lymphocyte tumor tissue with Mouse anti-CD43/Sialophorin antibody (NBP3-32154) at 1/1,000 dilution. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (NBP3-32154) at 1/1,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Immunocytochemistry/ Immunofluorescence: CD43/Sialophorin Antibody (A2F8-R) [NBP3-32154] - Immunocytochemistry analysis of U-937 (positive) and HT-29 (negative) labeling CD43/Sialophorin with Mouse anti-CD43/Sialophorin antibody (NBP3-32154) at 1/250 dilution. Cells were fixed in 4% paraformaldehyde for 20 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 5 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Mouse anti-CD43/Sialophorin antibody (NBP3-32154) at 1/250 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Mouse IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI. beta Tubulin (red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Rabbit IgG H&L (iFluor™ 594) were used as the secondary antibody at 1/1,000 dilution.

Background

CD43 is a key glycoprotein of thymocytes and T lymphocytes, which affects the physicochemical properties of the T-cell surface and plays a role in lectin binding. This antibody contains an extended rodlike structure that may protrude above the glycocalyx of the cell, allowing accessibility of multiple glycan chains for binding. During T-cell activation CD43 is actively removed from the T-cell-antigen-presenting cell contact site, thus suggesting CD43's role in negative regulation of the adaptive immune response.
