Safety Data Sheet (SDS) PerCP/Cy55 Anti-mouse CD49d Antibody     Product Data Sheet (PDF)    
PerCP/Cy5.5 Anti-mouse CD49d Antibody
1118095 25 µg $120.00       
1118100 100 µg $300.00       
Clone: R1-2
Isotype: Rat IgG2b, κ
Reactivity: Mouse
Immunogen: AKR/Cum mouse spontaneous T lymphoma line TK1
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography and conjugated with PerCP/Cy5.5 under optimal conditions. The solution is free of unconjugated PerCP/Cy5.5 and unconjugated antibody.
Concentration: 0.2 mg/ml
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
Application:

FC - Quality tested

Application Notes:

The R1-2 antibody has been shown to partially block CD49d mediated interactions and, in combination with the 9C10 (MFR4.B) antibody, completely blocks VCAM-1 binding to VLA-4. Additional reported applications (for the relevant formats) include: in vitro and in vivo blocking of cell-cell adhesion and T cell costimulation1-4, immunoprecipitation1, and immunohistochemistry of frozen sections5.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.5 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

* PerCP/Cy5.5 has a maximum absorption of 482 nm and a maximum emission of 690 nm.

Description:

CD49d is a 150 kD glycoprotein, also known as α4 integrin or VLA-4 α chain. It is a member of the integrin family, expressed on T and B cells, monocytes, eosinophils, basophils, mast cells, thymocytes, NK cells, and dendritic cells. CD49d is a heterodimer expressed with either of two β chains, β1 (CD29) or β7, to form the VLA-4 (integrin α4β1) or LPAM-1 (integrin α4β7) complexes. CD49d plays a critical role in adhesion and T cell costimulation. The primary ligands for CD49d are VCAM-1, MAdCAM-1, and fibronectin.

Other Names: α4 integrin, VLA-4 α chain, integrin α4, ITGA4
