Gene name
ICOS

简介
ICOS is a key protein for T cell function and can significantly enhance various T cell responses to foreign antigens. It plays a crucial role in promoting T cell proliferation, lymphokine secretion and upregulation of intercellular interaction molecules, and promoting efficient secretion of B cell antibodies. ICOS Protein, Rat (C137S, C138S, HEK293, His) is the recombinant rat-derived ICOS protein, expressed by HEK293, with C-His labeled tag.

Stability Test
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.
-
Storage & Shelf Life
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.
-
Shipping
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.
