SCYE1(small inducible cytokine subfamily E, member 1) is also named as EMAP2, AIMP1. The human cDNA encodes a 312-amino acid polypeptide that the predicted 34-kDa precursor can be cleaved to produce an active 20-kDa product(PMID:7929199). SCYE1 is secreted as a result of various stimuli, including TNF-α, heat shock, and hypoxia, and that it acts as a multifunctional cytokine on both endothelial and immune cells. Defects in AIMP1 are the cause of leukodystrophy hypomyelinating type 3 (HLD3). It has 2 isoforms produced by alternative splicing and the protein can exsit as a dimer.

Reconstitution |
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions. |
Shipping and Storage
