IL-31 Protein, Human (HEK293)

IL-31 is a multifunctional cytokine that activates STAT3 through IL-31 heterodimeric receptors (IL31RA and OSMR) and may activate STAT1 and STAT5. IL-31 is known for its involvement in skin immunity, where it regulates immune responses. IL-31 Protein, Human (HEK293) is the recombinant human-derived IL-31 protein, expressed by HEK293, with tag free.

IL-31, a cytokine with diverse functions, acts by activating STAT3, and potentially STAT1 and STAT5, utilizing the IL-31 heterodimeric receptor formed by IL31RA and OSMR. This activation mechanism has been implicated in skin immunity, highlighting its role in modulating immune responses. Additionally, IL-31 exhibits the capacity to enhance myeloid progenitor cell survival in vitro, emphasizing its involvement in cellular processes beyond immune regulation. Furthermore, IL-31 induces the expression of key genes, such as RETNLA and serum amyloid A protein, in macrophages, suggesting a broader impact on inflammatory and immune-related pathways.

Full Length of Mature Protein

Approximately 18-20 kDa,based on SDS-PAGE under reducing conditions,due to the glycosylation.

Greater than 90% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from 0.22 μm filtered solution of PBS, pH7.4 with trehalose as protectant.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
