Product introduction

Recombinant Human Fas Ligand/TNFSF6 Protein is expressed in HEK293 cells with a His tag at the N-terminus. It contains amino acid residues Pro134-Leu281 (accession: AAH17502.1).

Product details

Molecular aliases: APTL; CD95-L; Fas ligand; APT1LG1; TNFSF6; FASLG; ALPS1B; CD178; FASL; TNLG1A; CD95L
Protein length: Pro134-Leu281
Expression system: HEK293
Molecular weight: The protein has a predicted MW of 18 kDa. Due to glycosylation, the protein migrates to 20-35 kDa based on Bis-Tris PAGE result.
Purity: > 95% as determined by Bis-Tris PAGE
Endotoxin: Less than 1 EU per μg by the LAL method.
Formulation: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
State: Lyophilized
Storage: -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Reconstitution: Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

Background

Fas ligand (FasL, CD95L) is a 40-kDa type II transmembrane protein that binds to Fas (CD95) receptors and promotes programmed cell death. Fas receptors are expressed at higher levels in many tumors than in normal cells. Somewhat paradoxically, elimination of Fas or FasL from tumors also leads to death induced by CD95 receptor/ligand elimination (DICE).
