TNFSF9/TNF ligand superfamily member 9/4-1BBL | E21-H04

TNFSF9/TNF ligand superfamily member 9/4-1BBL | E21-H04 | Gentaur UK, US & Europe Distribution

Short Description: Recombinant Human 4-1BB ligand is produced by our E.coli expression system and the target gene encoding Arg71-Glu254 is expressed with a 6His tag at the C-terminus.

Shipping: Ambient

Formulation: Lyophilized from a 0.2 m filtered solution of 20mM PB150mM NaCl, pH7.4.

Storage: Lyophilized protein should be stored at < -20C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20C for 3 months.

Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 g /ml.
Dissolve the lyophilized protein in ddH2O.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

Purity: Greater than 95% as determined by reducing SDS-PAGE.

Endotoxin: Less than 0.1 ng/g (1 IEU/g) as determined by LAL test.

Background: Tumor necrosis factor ligand superfamily member 9 (4-1BBL) is single-pass type II membrane protein which is a member of the the tumor necrosis factor family. 4-1BBL is a 254 amino acids cytokine that is expressed in brain, placenta, lung, skeletal muscle and kidney. TNFSF9 has been shown to reactivate anergic T lymphocytes in addition to promoting T lymphocyte proliferation. This cytokine may have a role in activation-induced cell death (AICD) and cognate interactions between T-cells and B-cells/macrophages. It has also been shown to be required for the optimal CD8 responses in CD8 T cells, and is thought to be involved in T cell-tumor cell interaction.

Species: Human
