LAG3/CD223/Lymphocyte activation gene 3 Protein | E21-J91 | Gentaur UK, US & Europe Distribution

Short Description: Recombinant Human Lymphocyte Activation Gene 3 Protein is produced by our Mammalian expression system and the target gene encoding Leu23-Gly434 is expressed with a 6His tag at the C-terminus.

Shipping: Ambient

Formulation: Lyophilized from a 0.2 m filtered solution of 20mM PB, 150mM NaCl, pH 7.4.

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: Human Lymphocyte activation gene 3 protein ( LAG3) is a member of immunoglobulin (Ig) superfamily. LAG3 contains 4 extracellular Ig-like domains. The LAG3 gene contains 8 exons. LAG3 is involved in lymphocyte activation and can bind to HLA class-II antigens. It is selectively expressed in activated T and NK cells. LAG3 has a negative regulatory function in T cells and acts as as a new marker of T cell induced B cell activation. As a soluble molecule, LAG3 activates antigen-presenting cells through MHC class II signaling. It can lead to increased antigen-specific T-cell responses in vivo. LAG-3 has higher affinity to MHC class II than CD4.
