Description: Recombinant Human CD157 Protein is produced by mammalian expression system and the target gene encoding Gly29-Lys292 is expressed with a 6His at the C-terminus. Form: Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4. Gene Symbol: BST1 Alternative Names: ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase 2; ADP-ribosyl cyclase 2; Bone marrow stromal antigen 1; BST-1; Cyclic ADP-ribose hydrolase 2; cADPr hydrolase 2; CD157Entrez Gene (Human): 683SwissProt (Human): Q10588Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : GARARWRGEG TSAHLRDIFL GRCAEYRALL SPEQRNKNCT AIWEAFKVAL DKDPCSVLPS DYDLFINLSR HSIPRDKSLF WENSHLLVNS FADNTRRFMP LSDVLYGRVA DFLSWCRQKN DSGLDYQSCP TSEDCENNPV DSFWKRASIQ YSKDSSGVIH VMLNGSEPTG AYPIKGFFAD YEIPNLQKEK ITRIEIWVMH EIGGPNVESC GEGSMKVLEK RLKDMGFQYS CINDYRPVKL LQCVDHSTHP DCALKSAAAA TQRKHHHHHH 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.
