Description: Recombinant Human IZUMO4 Protein is produced by mammalian expression system and the target gene encoding His16-His214 is expressed with a Fc tag at the C-terminus. Form: Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4. Gene Symbol: IZUMO4 Alternative Names: C19orf36; Izumo sperm-egg fusion protein 4; Sperm 22 kDa protein c113Entrez Gene (Human): 113177SwissProt (Human): Q1ZYL8Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : HGCLHCHSNF SKKFSFYRHH VNFKSWWVGD IPVSGALLTD WSDDTMKELH LAIPAKITRE KLDQVATAVY QMMDQLYQGK MYFPGYFPNE LRNIFREQVH LIQNAIIESR IDCQHRCGIF QYETISCNNC TDSHVACFGY NCESSAQWKS AVQGLLNYIN NWHKQDTSMS LVSPALRCLE PPHLANLTLE DAAECLKQHV DDIEGRMDEP KSCDKTHTCP PCPAPELLGG PSVFLFPPKP KDTLMISRTP EVTCVVVDVS HEDPEVKFNW YVDGVEVHNA KTKPREEQYN STYRVVSVLT VLHQDWLNGK EYKCKVSNKA LPAPIEKTIS KAKGQPREPQ VYTLPPSREE MTKNQVSLTC LVKGFYPSDI AVEWESNGQP ENNYKTTPPV LDSDGSFFLY SKLTVDKSRW QQGNVFSCSV MHEALHNHYT QKSLSLSPGK 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.
