Specificity: Specific for active conformation of human b1 integrins. Does not augment the affinity of beta 1 for ligands. Species cross-reactivity: rat.
Immunogen: Human b1 integrins purified from Triton X-100 lysates of human lung, liver, and skeletal muscle tissues. Specifically selected due to its increased reactivity with T-lymphoblasts upon Mn2+ stimulation.
