Description：Recombinant Mouse IL-21R Protein is produced by mammalian expression system and the target gene encoding Cys20-Pro236 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：IL21RAlternative Names：NILR; Interleukin-21 receptor; IL-21 receptor; IL-21R; Novel interleukin receptor; CD360 Entrez Gene (Mouse)： 60504; SwissProt (Mouse)： Q9JHX3; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：CLDLTCYTDY LWTITCVLET RSPNPSILSL TWQDEYEELQ DQETFCSLHR SGHNTTHIWY TCHMRLSQFL SDEVFIVNVT DQSGNNSQEC GSFVLAESIK PAPPLNVTVA FSGRYDISWD SAYDEPSNYV LRGKLQYELQ YRNLRDPYAV RPVTKLISVD SRNVSLLPEE FHKDSSYQLQ VRAAPQPGTS FRGTWSEWSD PVIFQTQAGE PEAGWDPHHH HHHDirections 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.
