Description: Recombinant Human TGFA Protein is produced by E. coli expression system and the target gene encoding Val40-Ala89 is expressed. Form: Lyophilized from a 0.2 μM filtered solution of 10mM Acetic Acid. Gene Symbol: TGFA Alternative Names: Protransforming growth factor alphaEntrez Gene (Human): 7039SwissProt (Human): P01135Purity : Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure : VVSHFNDCPD SHTQFCFHGT CRFLVQEDKP ACVCHSGYVG ARCEHADLLA 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.
