Description

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.

Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

> 98% by SDS-PAGE and HPLC analyses.

Biological Activity

Fully biologically active when compared to standard. The ED50 as determined by the apoptotic effect using serum free human MCF-7 cells is less than 40 ng/mL, corresponding to a specific activity of > 2.5 × 104 IU/mg.

Endotoxin

< 1.0 EU per 1μg of the protein by the LAL method.

Formulation

Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.

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.
