Scientific Data Images for Human CD1a Antibody

Detection of CD1a in MOLT‑4 Human Cell Line by Flow Cytometry.

MOLT-4 human acute lymphoblastic leukemia cell line was stained with Mouse Anti-Human CD1a Monoclonal Antibody (Catalog # MAB7076, filled histogram) or isotype control antibody (MAB002, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG Secondary Antibody (F0102B).

CD1a in MOLT‑4 Human Cell Line.

CD1a was detected in immersion fixed MOLT-4 human acute lymphoblastic leukemia cell line using Mouse Anti-Human CD1a Monoclonal Antibody (Catalog # MAB7076) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; NL007) and counterstained with DAPI (blue). Specific staining was localized to surface and cytoplasm. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Detection of CD1a in Human Skin.

CD1a was detected in immersion fixed paraffin-embedded sections of Human Skin using Mouse Anti-Human CD1a Monoclonal Antibody (Catalog # MAB7076) at 3 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to Langerhan's cells.

Background: CD1a

CD1a is a 49 kDa transmembrane glycoprotein in the CD1 family of glycolipid antigen-presenting MHC-like molecules. CD1a contains one Ig-like domain in its extracellular region. It is expressed by most nonhuman mammals but not by mice or rats. Complexes of CD1a with beta2-microglobulin and endogenous glycolipids are constitutively expressed on antigen presenting cells, cortical thymocytes, and Langerhans cells. CD1a is a target of autoreactive Th22 helper T cells in the skin.
