Description: Recombinant Human ROBO4 Protein is produced by mammalian expression system and the target gene encoding Gln28-Arg467 is expressed with a Fc tag at the C-terminus. Form: Lyophilized from a 0.2 μM filtered solution of PBS, pH 7.4. Gene Symbol: ROBO4 Alternative Names: Roundabout homolog 4; Magic roundaboutEntrez Gene (Human): 54538SwissProt (Human): Q8WZ75Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : QDSPPQILVH PQDQLFQGPG PARMSCQASG QPPPTIRWLL NGQPLSMVPP DPHHLLPDGT LLLLQPPARG HAHDGQALST DLGVYTCEAS NRLGTAVSRG ARLSVAVLRE DFQIQPRDMV AVVGEQFTLE CGPPWGHPEP TVSWWKDGKP LALQPGRHTV SGGSLLMARA EKSDEGTYMC VATNSAGHRE SRAARVSIQE PQDYTEPVEL LAVRIQLENV TLLNPDPAEG PKPRPAVWLS WKVSGPAAPA QSYTALFRTQ TAPGGQGAPW AEELLAGWQS AELGGLHWGQ DYEFKVRPSS GRARGPDSNV LLLRLPEKVP SAPPQEVTLK PGNGTVFVSW VPPPAENHNG IIRGYQVWSL GNTSLPPANW TVVGEQTQLE IATHMPGSYC VQVAAVTGAG AGEPSRPVCL LLEQAMERAT QEPSEHGPWT LEQLRATLKR VDDIEGRMDE PKSCDKTHTC PPCPAPELLG GPSVFLFPPK PKDTLMISRT PEVTCVVVDV SHEDPEVKFN WYVDGVEVHN AKTKPREEQY NSTYRVVSVL TVLHQDWLNG KEYKCKVSNK ALPAPIEKTI SKAKGQPREP QVYTLPPSRE EMTKNQVSLT CLVKGFYPSD IAVEWESNGQ PENNYKTTPP VLDSDGSFFL YSKLTVDKSR WQQGNVFSCS VMHEALHNHY TQKSLSLSPG K 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.
