Description: Recombinant Mouse FSTL1 Protein is produced by mammalian expression system and the target gene encoding Glu19-Ile306 is expressed with a Fc tag at the C-terminus. Form: Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4. Gene Symbol: FSTL1 Alternative Names: FRP; Follistatin-related protein 1; Follistatin-like protein 1Entrez Gene (Mouse) : 14314SwissProt (Mouse) : Q62356Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : EEEPRSKSKI CANVFCGAGR ECAVTEKGEP TCLCIEQCKP HKRPVCGSNG KTYLNHCELH RDACLTGSKI QVDYDGHCKE KKSASPSASP VVCYQANRDE LRRRLIQWLE AEIIPDGWFS KGSNYSEILD KYFKSFDNGD SHLDSSEFLK FVEQNETAIN ITTYADQENN KLLRSLCVDA LIELSDENAD WKLSFQEFLK CLNPSFNPPE KKCALEDETY ADGAETEVDC NRCVCSCGHW VCTAMTCDGK NQKGVQTHTE EEKTGYVQEL QKHQGTAEKT KKVNTKEIVD DIEGRMDEPK SCDKTHTCPP CPAPELLGGP SVFLFPPKPK DTLMISRTPE VTCVVVDVSH EDPEVKFNWY VDGVEVHNAK TKPREEQYNS TYRVVSVLTV LHQDWLNGKE YKCKVSNKAL PAPIEKTISK AKGQPREPQV YTLPPSREEM TKNQVSLTCL VKGFYPSDIA VEWESNGQPE NNYKTTPPVL DSDGSFFLYS KLTVDKSRWQ QGNVFSCSVM HEALHNHYTQ KSLSLSPGK 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.
