Form	Lyophilized
Storage buffer	Lyophilized from a solution in PBS pH 7.4, 1 mM EDTA, 4% Trehalose, 1% Mannitol. Please refer to the specific buffer information in the hardcopy of datasheet or the lot-specific COA.
Reconstitution	Reconstitute in sterile water for a stock solution. Adjust the volume of sterile water so that, after reconstitution, the final stock concentration matches the value indicated on the product label or datasheet. RECONSTITUTION PROTOCOL 1. Allow the product to be reconstituted and the reconstitution diluent to reach room temperature. 2. Tap or briefly centrifuge the product vial before opening to dislodge any lyophilized material that may be dispersed on the wall or cap of the vial. 3. Use the diluent and stock concentration recommended in the product datasheet. If preparing a stock concentration higher than recommended, contact Technical Service. 4. After adding the diluent, re-cap the vial and invert gently by hand or place on a slow rocking platform to allow the reconstitution diluent to coat all the surfaces inside the vial. Note: Do not mix by vortexing or by pipetting the material up and down. 5. Allow the vial to sit at room temperature with gentle agitation for at least 15 minutes before aliquotting or using. 6. Store the reconstituted material in single use aliquots in polypropylene or siliconized tubes. Aliquots of 10 μL or larger are recommended.
Shipping	In general, proteins are provided as lyophilized powder/frozen liquid. They are shipped out with dry ice/blue ice unless customers require otherwise.
Stability and Storage	Use a manual defrost freezer and avoid repeated freeze thaw cycles. Store at 2 to 8°C for frequent use. Store at -20 to -80°C for twelve months from the date of receipt.
Alternate Names	IL-31RA, Interleukin-31 receptor subunit alpha, IL31RA, hGLM-R, ZcytoR17, IL-31R-alpha, GPL, CRL3, Cytokine receptor-like 3, IL-31R subunit alpha, IL-31 receptor subunit alpha, Gp130-like receptor, GLM-R, Gp130-like monocyte receptor
Background	Interleukin-31 receptor subunit alpha (IL31RA) is a ~82 kDa protein. Associates with OSMR to form the interleukin-31 receptor which activates STAT3 and to a lower extent STAT1 and STAT5. May function in skin immunity. Mediates IL31-induced itch, probably in a manner dependent on cation channels TRPA1 and TRPV1. Positively regulates numbers and cycling status of immature subsets of myeloid progenitor cells in bone marrow in vivo and enhances myeloid progenitor cell survival in vitro. 1. Ghilardi, N. et al.
