Scientific Data Images for Human CD5 Antibody

Detection of Human CD5 antibody by Western Blot.

Detection of Human CD5 by Western Blot.

Western blot shows lysates of Jurkat human acute T cell leukemia cell line and CEM human T-lymphoblastoid cell line. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human CD5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1636) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for CD5 at approximately 67 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

CD5 antibody in Human PBMCs by Immunocytochemistry (ICC).

CD5 in Human PBMCs.

CD5 was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using Goat Anti-Human CD5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1636) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cell surfaces. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Detection of Human CD5 antibody by Simple WesternTM.

Detection of Human CD5 by Simple WesternTM.

Simple Western lane view shows lysates of CEM human T-lymphoblastoid cell line, loaded at 0.2 mg/mL. A specific band was detected for CD5 at approximately 93 kDa (as indicated) using 10 µg/mL of Goat Anti-Human CD5 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1636). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: CD5

CD5, also known as Leu-1, is a type I transmembrane protein belonging to the scavenger receptor cysteine-rich (SRCR) superfamily. It is expressed on thymocytes, T cells and the B1a subpopulation of B cells. CD5 binds the C-type lectin, CD72, and modulates signaling through the antigen receptors on T and B cells. CD5 has been shown to provide either positive or negative co-stimulatory signals depending on cell type to regulate immune responses.
