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: FGF4 Alternative 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 KS3Entrez Gene (Human): 2249SwissProt (Human): P08620Purity : 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 LPRL 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.
