Description：Recombinant Human CALU Protein is produced by Mammalian expression system and the target gene encoding Lys20-Phe315 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4.Gene Symbol：CALUAlternative Names：Calumenin; Crocalbin; IEF SSP 9302 Entrez Gene (Human)： 813; SwissProt (Human)： O43852; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：KPTEKKDRVH HEPQLSDKVH NDAQSFDYDH DAFLGAEEAK TFDQLTPEES KERLGKIVSK IDGDKDGFVT VDELKDWIKF AQKRWIYEDV ERQWKGHDLN EDGLVSWEEY KNATYGYVLD DPDPDDGFNY KQMMVRDERR FKMADKDGDL IATKEEFTAF LHPEEYDYMK DIVVQETMED IDKNADGFID LEEYIGDMYS HDGNTDEPEW VKTEREQFVE FRDKNRDGKM DKEETKDWIL PSDYDHAEAE ARHLVYESDQ NKDGKLTKEE IVDKYDLFVG SQATDFGEAL VRHDEFVDHH HHHHDirections 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 1X PBS. 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.
