Description：Recombinant Human FGF4 Protein is produced by E.coli expression system and the target gene encoding Ser54-Leu206 is expressed.Form：Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.Gene Symbol：FGF4Alternative Names：HST; HSTF1; KS3; Fibroblast growth factor 4; FGF-4; Heparin secretory-transforming protein 1; HST; HST-1; HSTF-1; Heparin-binding growth factor 4; HBGF-4; Transforming protein KS3 Entrez Gene (Human)： 2249; SwissProt (Human)： P08620; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MSLARLPVAA QPKEAAVQSG AGDYLLGIKR LRRLYCNVGI GFHLQALPDG RIGGAHADTR DSLLELSPVE RGVVSIFGVA SRFFVAMSSK GKLYGSPFFT DECTFKEILL PNNYNAYESY KYPGMFIALS KNGKTKKGNR VSPTMKVTHF LPRLDirections 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.
