Sterile Filtered White lyophilized (freeze-dried) powder.
Reactivity:
Pig
Description:
Interleukin-1A Porcine Recombinant produced in E. coli is single, a non-glycosylated, Polypeptide chain containing 158 amino acids and having a molecular mass of 18076 Dalton. The IL-1A is purified by proprietary chromatographic techniques.
Function:
Produced by activated macrophages, IL-1 stimulates thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity. IL-1 proteins are involved in the inflammatory response, being identified as
Cell localization:
Secreted. The lack of a specific hydrophobic segment in the precursor sequence suggests that IL-1 is released by damaged cells or is secreted by a mechanism differing from that used for other secretory proteins.
Purification:
Greater than 95.0% as determined by (a) Analysis by RP-HPLC and (b) Analysis by SDS-PAGE.
Storage conditions:
Lyophilized Interleukin-1 alpha although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution IL1A should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recomme
Aa sequence:
The sequence of the first five N-terminal amino acids was determined and was found to be Ser-Ala-Thr-Tyr-Ser.
