FC - Quality tested

Application Notes:

Additional reported applications (for the relevant format) include: inhibition of cell adhesion and cytokine production1,2.

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 ≤1.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

C1300 (mouse adenocarcinoma cell line)

C1300 (mouse adenocarcinoma cell line) cells were stained with purified CD49a (clone HMα1, filled histogram) or Armenian hamster IgG (open histogram), followed by anti-hamster IgG PE.


CD49a is a 1179 aa, type I transmembrane glycoprotein also known as α1 integrin, VLA-1 α chain, or integrin α1. It associates antibody v042010 with CD29 (β1 integrin) to form the VLA-1 complex, a collagen IV and alminin-1 receptor that is expressed on activated T cells, smooth muscle cells, endothelial cells, neuronal cells, fibroblasts, and mesenchymal cells. CD49a is an adhesion molecule and is involved in the regulation of leukocyte migration, T cell proliferation, and cytokine production.

Other Names: Very late antigen 1 (VLA1), integrin alpha 1 (ITGA1)
Structure: 1179 aa, type I transmembrane glycoprotein
