Description: Recombinant Human INSL4 Protein is produced by mammalian expression system and the target gene encoding Ala26-Thr139 is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μM filtered solution of 20mM Tris, 150mM NACl, pH 8.0. Gene Symbol: INSL4 Alternative Names: Early placenta insulin-like peptide; EPIL; Insulin-like peptide 4; PlacentinEntrez Gene (Human): 3641SwissProt (Human): Q14641Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : AELRGCGPRF GKHLLSYCPM PEKTFTTTPG GWLLESGRPK EMVSTSNNKD GQALGTTSEF IPNLSPELKK PLSEGQPSLK KIILSRKKRS GRHRFDPFCC EVICDDGTSV KLCTVDHHHH HH 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.
