Recombinant Rat B7-1/CD80 Protein(HEK293), hFc

B7-1/CD80

B7-1/CD80, a type I membrane protein, is a member of the B7 family, with an extracellular immunoglobulin constant-like domain and a variable-like domain required for receptor binding.CD80 is also a transmembrane glycoprotein and a member of the Ig superfamily.CD80 has a crucial role in modulating T-cell immune function as a checkpoint protein at the immunological synapse.Its binding to CD28 or CTLA-4 receptors is integral to inducing T-cell proliferation and cytokine production.B7-1/CD80 Protein, Rat (HEK293, Fc) is the recombinant rat-derived B7-1/CD80 protein, expressed by HEK293 , with C-hFc labeled tag.

The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.
