CD1a Molecule (CD1A) antibody (FITC)

Antigen: CD1a Molecule (CD1A)

Synonyms: R4, T6, CD1, FCB6, HTA1, CD1A, CD1.1, CD1.2, CD1A2

Clonality: Monoclonal (HI149)

Host: Mouse

Reactivity: Human

Conjugate: FITC

Application: Flow Cytometry (FACS)

Catalog no.: ABIN94019

Additional Information

Alternative name: CD1a

Gene ID: 1q22-q23

Immunogen: Human thymocytes

Isotype: IgG1

Clone: HI149

Description: CD1a, together with CD1b and c, belongs to group 1 of CD1 glycoproteins. These proteinsserve as antigen-presenting molecules for a subset of T cells that responds to specific lipidsand glycolipids found in the cell walls of bacterial pathogens or self-glycolipid antigens suchas gangliosides, and they have also roles in antiviral immunity. Unlike CD1b, CD1a isexcluded from late endosomal compartments and instead traffics independently in therecycling pathway of the early endocytic system, and CD1a antigen presentation isindependent upon vesicular acidification.

Specificity: The antibody HI149 reacts with CD1a (T6), a 49 KDa polypeptide associated withbeta2-microglobulin expressed on cortical thymocytes (strongly), Langerhans cells, dendriticcells and some T cell leukemias and lymphomas.The antibody does not react with peripheral blood T and B lymphocytes, monocytes,granulocytes, platelets and erythrocytes.HLDA V, WS Code CD01.01

Application Details

Application Notes: The reagent is designed for Flow Cytometry analysis of human blood cells using 20 µl reagent / 100 µl of whole blood or 10 6 cells in a suspension. The content of a vial (2 ml) is sufficient for 100 tests.

Buffer: The reagent is provided in phosphate buffered saline (PBS) containing 15 mM sodium azideand 0.2% (w/v) high-grade protease free Bovine Serum Albumin (BSA) as a stabilizing agent.

Storage: Store in the dark at 2-8 o C. Do not freeze. Avoid prolonged exposure to light. Do not use after expiration date stamped on vial label.Short-term exposure to room temperature should not affect the quality of the reagent.However, if reagent is stored under any conditions other than those specified, the conditions must be verified by the user.
