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-5R subunit alpha, IL-5 receptor subunit alpha, IL5RA, IL-5RA, IL-5R-alpha, Interleukin-5 receptor subunit alpha, CDw125, CD125, IL5R
Background	Interleukin-5 receptor subunit alpha (CD125/IL5RA) is a ~47 kDa protein. Cell surface receptor that plays an important role in the survival, differentiation, and chemotaxis of eosinophils. Acts by forming a heterodimeric receptor with CSF2RB subunit and subsequently binding to interleukin-5. In unstimulated conditions, interacts constitutively with JAK2. Heterodimeric receptor activation leads to JAK2 stimulation and subsequent activation of the JAK-STAT pathway. 1. Monahan, J. et al. (1997) Journal of immunology (Baltimore, Md. : 1950) 159, 4024-34.
