Cat. No.:

CRI136B-GMP pdf (datasheet)

Quantity/Size:

100 μg

Description:

Interleukin-1 alpha (IL-1α) is a non-secreted proinflammatory cytokine produced mainly by activated macrophages, as well as neutrophils, epithelial cells, and endothelial cells. It possesses metabolic, physiological, hematopoietic activities, and plays one of the central roles in the regulation of the immune responses. Both IL-1α and IL-1β binds to the same receptor and has similar identical biological properties. Among various species, the amino acid sequence of mature IL-1α is conserved 60% to 70% and human IL-1 has been found to be biologically active on murine cell lines.
Manufacturing and testing of this product complies with ICH Q7 guidelines.

Storage/Stability:

Lyophilized vial is shipped at ambient temperature. Immediately upon receipt, store unopened vial at -20°C (manual defrost freezer) or -80°C for up to 36 months. Upon reconstitution, prepare working aliquots and store at -20°C (manual defrost freezer) or -80°C. It is recommended that a carrier protein such as 0.1% HSA or BSA is added for long term storage. For short term storage reconstituted material is stable for 4-6 weeks when stored at 2-8°C. Avoid repeated freeze-thaw cycles.
