Description: Recombinant Human CFHR4 Protein is produced by mammalian expression system and the target gene encoding Glu20-Glu578 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: CFHR4 Alternative Names: CFHL4; FHR4; Complement factor H-related protein 4; FHR-4Entrez Gene (Human): 10877SwissProt (Human): Q92496Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : EVKPCDFPEI QHGGLYYKSL RRLYFPAAAG QSYSYYCDQN FVTPSGSYWD YIHCTQDGWS PTVPCLRTCS KSDVEIENGF ISESSSIYIL NEETQYNCKP GYATAEGNSS GSITCLQNGW STQPICIKFC DMPVFENSRA KSNGMWFKLH DTLDYECYDG YESSYGNTTD SIVCGEDGWS HLPTCYNSSE NCGPPPPISN GDTTSFPQKV YLPWSRVEYQ CQSYYELQGS KYVTCSNGDW SEPPRCISMK PCEFPEIQHG HLYYENTRRP YFPVATGQSY SYYCDQNFVT PSGSYWDYIH CTQDGWLPTV PCLRTCSKSD IEIENGFISE SSSIYILNKE IQYKCKPGYA TADGNSSGSI TCLQNGWSAQ PICIKFCDMP VFENSRAKSN GMRFKLHDTL DYECYDGYEI SYGNTTGSIV CGEDGWSHFP TCYNSSEKCG PPPPISNGDT TSFLLKVYVP QSRVEYQCQS YYELQGSNYV TCSNGEWSEP PRCIHPCIIT EENMNKNNIQ LKGKSDIKYY AKTGDTIEFM CKLGYNANTS VLSFQAVCRE GIVEYPRCEH HHHHH 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. 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.
