Recombinant Cynomolgus IL-4 Protein (HEK293), C-hFc

IL-4

IL-4 protein has an important effect on B cell activation, acting as a costimulator for DNA synthesis and promoting the expression of class II MHC molecules on resting B cells. It enhances IgE and IgG1 secretion and cell surface expression while also regulating CD23 expression on lymphocytes and monocytes. IL-4 Protein, Cynomolgus (HEK293, Fc) is the recombinant cynomolgus-derived IL-4 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.
