Description：Recombinant Human CTF1 Protein is produced by E. coli expression system and the target gene encoding Met1-Ala201 is expressed with a 6His tag at the N-terminus.Form：Liquid in a 0.2 μM filtered solution of PBS, 2mM EDTA, 5% Trehalose, pH7.4.Gene Symbol：CTF1Alternative Names：Cardiotrophin-1; CT-1 Entrez Gene (Human)： 1489; SwissProt (Human)： Q16619; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MNHKVHHHHH HMSRREGSLE DPQTDSSVSL LPHLEAKIRQ THSLAHLLTK YAEQLLQEYV QLQGDPFGLP SFSPPRLPVA GLSAPAPSHA GLPVHERLRL DAAALAALPP LLDAVCRRQA ELNPRAPRLL RRLEDAARQA RALGAAVEAL LAALGAANRG PRAEPPAATA SAASATGVFP AKVLGLRVCG LYREWLSRTE GDLGQLLPGG SADirections 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：Store it at -20°C to -80°C for one year. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
