Description: Recombinant Human FOLR1 Protein is produced by mammalian expression system and the target gene encoding Arg25-Ser234 is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μM filtered solution of PBS, pH 7.4. Gene Symbol: FOLR1 Alternative Names: FOLR; Folate receptor alpha; FR-alpha; Adult folate-binding protein; FBP; Folate receptor 1; Folate receptor, adult; KB cells FBP; Ovarian tumor-associated antigen MOv18Entrez Gene (Human): 2348SwissProt (Human): P15328Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : RIAWARTELL NVCMNAKHHK EKPGPEDKLH EQCRPWRKNA CCSTNTSQEA HKDVSYLYRF NWNHCGEMAP ACKRHFIQDT CLYECSPNLG PWIQQVDQSW RKERVLNVPL CKEDCEQWWE DCRTSYTCKS NWHKGWNWTS GFNKCAVGAA CQPFHFYFPT PTVLCNEIWT HSYKVSNYSR GSGRCIQMWF DPAQGNPNEE VARFYAAAMS VDHHHHHH 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 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.
