Background
Inhibitory receptor involved in the down-regulation of the immune response and the development of immune tolerance. Receptor for FN1. Receptor for apolipoprotein APOE. Receptor for ALCAM/CD166. Inhibits receptor-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions. Inhibits FCGR1A/CD64-mediated monocyte activation by inducing phosphatase-mediated down-regulation of the phosphorylation of multiple proteins including LCK, SYK, LAT and ERK, leading to a reduction in TNF production. This inhibition of monocyte activation occurs at least in part via binding to FN1. Inhibits T cell proliferation, inducing anergy, suppressing the differentiation of IFNG-producing CD8+ cytoxic T cells and enhancing the generation of CD8+ T suppressor cells. Induces up-regulation of CD86 on dendritic cells. Interferes with TNFRSF5-signaling and NF-kappa-B up-regulation.
Usage guide
Shipping
In general, recombinant proteins are provided as lyophilized powder which are shipped with blue ice. Bulk packages of recombinant proteins are provided as frozen liquid which are shipped with dry ice.
Storage
Please avoid repeated freeze-thaw cycles. Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃ It is recommended that aliquot the reconstituted solution to minimize freeze-thaw cycles.
Reconstitution
Reconstitute at 250 μg/ml in sterile water.
