Human IL31 Protein (Recombinant) - LS-G134056
Predicted Molecular Weight
Interleukin 31 (IL-31) is an immunoregulatory cytokine that is expressed by activated type 2 T helper (Th2) cells. IL-31 signals through a heterodimer receptor consisting of the IL-31 Receptor A (IL-31RA) and the oncostatin M receptor (OSMR), which are expressed on monocytes, epithelial cells, and keratinocytes. IL-31 promotes allergic reactions and inflammatory skin diseases.
Greater than 95% by reducing and non-reducing SDS-PAGE
Determined by STAT3 Activation in U-87 MG Cells; Detectable at <= 25 ng/ml
Less than 1.0 EU/µg protein (determined by LAL method).
Lyophilized from 20 mM Sodium Phosphate, 50 mM NaCl, pH 7.5
Centrifuge vial before opening. Reconstitute with sterile water at 0.1 mg/mL. Suspend the product by gently pipetting the recommended solution down the sides of the vial. Do not vortex. Allow several minutes for complete reconstitution.
Shipped at room temperature. Prior to reconstitution, store at -20°C. For prolonged storage, dilute to working aliquots in a 0.1% BSA solution. Store at -80°C and avoid freeze-thaw cycles.
