Description：Recombinant Human EFNA3 Protein is produced by Mammalian expression system and the target gene encoding Gln23-Ser211 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.2.Gene Symbol：EFNA3Alternative Names：EFL2; EPLG3; LERK3; Ephrin-A3; EFL-2; EHK1 ligand; EHK1-L; EPH-related receptor tyrosine kinase ligand 3; LERK-3 Entrez Gene (Human)： 1944; SwissProt (Human)： P52797; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：QGPGGALGNR HAVYWNSSNQ HLRREGYTVQ VNVNDYLDIY CPHYNSSGVG PGAGPGPGGG AEQYVLYMVS RNGYRTCNAS QGFKRWECNR PHAPHSPIKF SEKFQRYSAF SLGYEFHAGH EYYYISTPTH NLHWKCLRMK VFVCCASTSH SGEKPVPTLP QFTMGPNVKI NVLEDFEGEN PQVPKLEKSV DHHHHHHDirections 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.
