Analysis Note

Measured by its ability to induce apoptosis in Jurkat cells.

Application

Fas Ligand (FASLG) human has been used for-the study of FASLG stimulation in luteal cells obtained from mid-corpus luteum (CL) andthe study of apoptosis induction and intracellular caspase-3 assay in human cells.

Biochem/physiol Actions

Fas ligand, a protein belonging to the tumor necrosis factor (TNF) family of cytokines, induces apoptosis in cells expressing the cell membrane receptor Fas (CD95/Apo-1).

FASLG (Fas ligand) and Fas receptor constitute the basic elements in apoptosis. Interaction of FASLG with Fas receptor leads to activation of caspase-8. This caspase in turn leads to activation of effector caspases such as caspase-3, -6 and -7. This cascade results in the hydrolysis of nuclear and cytoplasmic components. Expression of FASLG is induced by nuclear factor-κB (NFκB). NFκB/FASLG pathway facilitates the suppression of p,p′-DDT (dichlorodiphenoxytrichloroethane)-induced cell toxicity by vitamin C and E. In CD4⁺ T cells, this protein is expressed on stimulus by T-cell receptor (TCR), both during normal and pathological conditions, such as alcohol exposure.

General description

FASLG (Fas ligand) acts as a ligand for Fas receptor, and is a major protein involved in programmed cell death, apoptosis. Soluble Fas (sFAS) is usually detected in plasma prior to apoptosis.

Other Notes

Human Fas Ligand, N-terminal 6X histidine-tagged, encodes amino acids 134-281.

Physical form

Lyophilized from a 0.2 µm filtered solution in phosphate buffered saline containing 0.5 mg bovine serum albumin.
