Description: Recombinant Human EFNA1 Protein is produced by Mammalian expression system and the target gene encoding Asp19-Ser182 is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μM filtered solution of 20mM Tris, pH 8.0. Gene Symbol: EFNA1 Alternative Names: EPLG1; LERK1; TNFAIP4; Ephrin-A1; EPH-related receptor tyrosine kinase ligand 1; LERK-1; Immediate early response protein B61; Tumor necrosis factor alpha-induced protein 4; TNF alpha-induced protein 4Entrez Gene (Human): 1942SwissProt (Human): P20827Purity : Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure : DRHTVFWNSS NPKFRNEDYT IHVQLNDYVD IICPHYEDHS VADAAMEQYI LYLVEHEEYQ LCQPQSKDQV RWQCNRPSAK HGPEKLSEKF QRFTPFTLGK EFKEGHSYYY ISKPIHQHED RCLRLKVTVS GKITHSPQAH VNPQEKRLAA DDPEVRVLHS IAHSVDHHHH 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.
