Description：Recombinant Human Alpha-fetoglobulin Protein is produced by mammalian expression system and the target gene encoding Arg19-Val609 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.Gene Symbol：AFPAlternative Names：HPAFP; Alpha-fetoprotein; Alpha-1-fetoprotein; Alpha-fetoglobulin Entrez Gene (Human)： 174; SwissProt (Human)： P02771; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：RTLHRNEYGI ASILDSYQCT AEISLADLAT IFFAQFVQEA TYKEVSKMVK DALTAIEKPT GDEQSSGCLE NQLPAFLEEL CHEKEILEKY GHSDCCSQSE EGRHNCFLAH KKPTPASIPL FQVPEPVTSC EAYEEDRETF MNKFIYEIAR RHPFLYAPTI LLWAARYDKI IPSCCKAENA VECFQTKAAT VTKELRESSL LNQHACAVMK NFGTRTFQAI TVTKLSQKFT KVNFTEIQKL VLDVAHVHEH CCRGDVLDCL QDGEKIMSYI CSQQDTLSNK ITECCKLTTL ERGQCIIHAE NDEKPEGLSP NLNRFLGDRD FNQFSSGEKN IFLASFVHEY SRRHPQLAVS VILRVAKGYQ ELLEKCFQTE NPLECQDKGE EELQKYIQES QALAKRSCGL FQKLGEYYLQ NAFLVAYTKK APQLTSSELM AITRKMAATA ATCCQLSEDK LLACGEGAAD IIIGHLCIRH EMTPVNPGVG QCCTSSYANR RPCFSSLVVD ETYVPPAFSD DKFIFHKDLC QAQGVALQTM KQEFLINLVK QKPQITEEQL EAVIADFSGL LEKCCQGQEQ EVCFAEEGQK LISKTRAALG VHHHHHHDirections 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.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.
