Description: Recombinant Human CD125 Protein is produced by mammalian expression system and the target gene encoding Asp21-Glu335 is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4. Gene Symbol: IL5RA Alternative Names: IL5R; Interleukin-5 receptor subunit alpha; IL-5 receptor subunit alpha; IL-5R subunit alpha; IL-5R-alpha; IL-5RA; CDw125; CD125Entrez Gene (Human): 3568SwissProt (Human): Q01344Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : DLLPDEKISL LPPVNFTIKV TGLAQVLLQW KPNPDQEQRN VNLEYQVKIN APKEDDYETR ITESKCVTIL HKGFSASVRT ILQNDHSLLA SSWASAELHA PPGSPGTSIV NLTCTTNTTE DNYSRLRSYQ VSLHCTWLVG TDAPEDTQYF LYYRYGSWTE ECQEYSKDTL GRNIACWFPR TFILSKGRDW LAVLVNGSSK HSAIRPFDQL FALHAIDQIN PPLNVTAEIE GTRLSIQWEK PVSAFPIHCF DYEVKIHNTR NGYLQIEKLM TNAFISIIDD LSKYDVQVRA AVSSMCREAG LWSEWSQPIY VGNDEHHHHH H Directions for Use : Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. Quality Control : Endotoxin: Less than 0.1 ng/µg (1 IEU/µg) as determined by LAL test.Storage/Stability : Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
