CD74 antibody (FITC)

Catalog No. ABIN2144686

Product Details anti-CD74 Antibody (FITC)

Target: CD74 (HLA-DR-gamma (CD74))

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This CD74 antibody is conjugated to FITC

Application: Flow Cytometry (FACS), Western Blotting (WB), Immunofluorescence (IF), Immunohistochemistry (IHC), Immunoprecipitation (IP)

Characteristics: The 4ALN2 monoclonal antibody recognizes human CD74, also known as the MHC Class II-associated invariant chain. A 33-43 kDa nonpolymorphic type II membrane protein, CD74 is highly expressed on B cells and subsets of activated T cells, Langerhans cells, dendritic cells, and epithelial cells. Monocytes and macrophages also express CD74, but at lower levels. CD74 acts as a chaperone of MHC Class II (HLA-DR) proteins, promoting their translocation from the ER to endocytic compartments during antigen presentation. Activation of NFκB and ERK has been shown following CD74 interaction with CD44 and binding to the proinflammatory cytokine macrophage migration-inhibitory factor (MIF). CD74 also plays a role in the maturation of follicular B-cells and accumulation of marginal zone B-cells. CD74 has also been demonstrated to interact with CXCR2 and CXCR4.

Clone: 4ALN2

Isotype: IgG1 kappa

Application Details

Application Notes: Optimal working dilution should be determined by the investigator.

Assay Procedure:

• Take 100 μL peripheral blood anticoagulated by EDTA and add to the bottom of 5 mLtube,
• Add 10 μL labeled antibody to the bottom of flow tube mixing with the whole blood, incubate for 20 minutes at room temperature away from light,
• Add 2 ml1×RBC lysis buffer, incubate for 10 minutes away from light after mixing, dissolve red blood cells (recommended: RBC lysing Solution 10×,Cat.: FXP001),
• Sample tube is set to 1000 rpm centrifugation for 5 minutes, discard the supernatant,
• Add 2 mLPBS wash buffer to resuspend the cells, then1000 rpm centrifugation for 5 minutes, discard the supernatant,
• Add 0.5 mLPBS wash buffer to resuspend the cells and detect by flow cytometry (sample should be determined on the day on the machine and can also be added fixation overnight at 4 °C then measured).
• [PBS wash buffer: PBS +1 % FBS +0.1 % NaN3, Cat.: FXP005]
• [Cell fixation: 2 % formaldehyde solution]
