Description: Recombinant Human CD200R1 Protein is produced by mammalian expression system and the target gene encoding Ala27-Leu266 is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4. Gene Symbol: CD200R1 Alternative Names: CD200R; CRTR2; MOX2R; OX2R; Cell surface glycoprotein CD200 receptor 1; CD200 cell surface glycoprotein receptor; Cell surface glycoprotein OX2 receptor 1Entrez Gene (Human): 131450SwissProt (Human): Q8TD46Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : AAQPNNSLML QTSKENHALA SSSLCMDEKQ ITQNYSKVLA EVNTSWPVKM ATNAVLCCPP IALRNLIIIT WEIILRGQPS CTKAYKKETN ETKETNCTDE RITWVSRPDQ NSDLQIRTVA ITHDGYYRCI MVTPDGNFHR GYHLQVLVTP EVTLFQNRNR TAVCKAVAGK PAAHISWIPE GDCATKQEYW SNGTVTVKST CHWEVHNVST VTCHVSHLTG NKSLYIELLP VPGAKKSAKL VDHHHHHH 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.
