LAG3 Detection Set (Risk Free)

The lymphocyte activation gene-3 (LAG3) is a member of the immunoglobulin superfamily and binds MHC class II with high affinity (1), negatively regulating T-cell function and homeostasis (2) . It is expressed in B, T, and NK cells, monocytes, and dendritic cells (3), and acts to regulate T cell expansion (4) . LAG3 is also an important immune checkpoint protein, with anti-LAG3 antibodies activating T effector cells and affecting regulatory T cell functions. Furthermore LAG3 appears to act in a synergistic fashion with PD-1/PD-L1, suggesting that a dual antibody approach may prove useful in cancer immunotherapy. ProSci's Risk-FreeTM antibodies are mouse monoclonal antibodies made to improve in vivo studies. Unlike antibodies developed using proteins made in yeast or bacteria, Risk-FreeTM antibodies are developed with antigens expressed in mammalian cell lines, giving the most native post-translational modifications to the protein. Validated for flow cytometry and ELISA Rigorously tested for the following applications: Immunoblot Immunohistochemistry Immunocytochemistry Immunofluorescence Multiple antibodies per target allowing the user to choose the best antibody for their application Available individually or as a set Risk-FreeTM means they are guaranteed to work for their approved applications

Antibodies can be stored at 4˚ C for three months and -20˚ C, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.
