Background of Integrin alpha 1/CD49a

Integrin alpha 1 (ITGA1) chain associates with the beta 1 (ITGB1) chain to form a heterodimer that functions as a dual laminin/collagen receptor in neural cells and hematopoietic cells. ITGA1 has a 206-amino acid I domain in its N-terminal half, followed by 3 divalent cation-binding sites and a C-terminal transmembrane domain with a short cytoplasmic tail. It also has 28 potential N-glycosylation sites. Human ITGA1 was expressed in a mouse fibroblast cell line as a 180-kD protein. ITGA1 is involved in the early remodeling of osteoarthritic cartilage and plays an essential role in the regulation of mesenchymal stem cell proliferation and cartilage production. It also plays an essential role in the regulation of MSC proliferation and cartilage production.

We are currently using anti-Integrin alpha 1/ITGA1 antibody PA1045-1 for human tissue, and we are content with the IHC results. The species of reactivity given in the datasheet says human, mouse, rat. Is it true that the antibody can work on zebrafish tissues as well?

Verified Customer

Verified customer

Asked: 2019-12-09


The anti-Integrin alpha 1/ITGA1 antibody (PA1045-1) has not been validated for cross reactivity specifically with zebrafish tissues, though there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in zebrafish you can get your next antibody for free. Please contact me if I can help you with anything.

Why is my protein concentration value higher than expected when measuring absorbance at 280 nm? Keyword: absorption spectroscopy

Verified Customer

Verified customer

Asked: 2015-11-10


The antibody contains BSA, so the value tested was much higher than expected concentration. Other proteins the antibody contains make it difficult to test the concentration of target protein. Each vial of PA1045 contains 5mg BSA, 0.9mg NaCl, 0.2mg Na2HPO4, 0.05mg Thimerosal, 0.05mg NaN3. The antibody is affinity purified, and the antibody contains a small quantity of other rabbit IgG because purification rate cannot reach 100%.
