Description：Recombinant Human WNT3A Protein is produced by mammalian expression system and the target gene encoding Ser19-Lys352 is expressed with a fusion design at the N-terminus.Form：Lyophilized from a 0.2 μm filtered solution of 10mM PB, 5% Sucrose, 0.01% Tween 80, pH7.4.Gene Symbol：WNT3AAlternative Names：Protein Wnt-3a Entrez Gene (Human)： 89780; SwissProt (Human)： P56704; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Quality Control：Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.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. 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.
