Description: Recombinant Human UPP1 Protein is produced by E. coli expression system and the target gene encoding Met1-Ala173 is expressed with a 6His tag at the N-terminus. Form: Liquid in a 0.2 μM filtered solution of 20mM Tris, 200mM NaCl, 1mM DTT, pH 8.0. Gene Symbol: UPP1 Alternative Names: UP; Uridine phosphorylase 1; UPase 1; UrdPase 1Entrez Gene (Human): 7378SwissProt (Human): Q16831Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : MGSSHHHHHH SSGLVPRGSH MQRKLKVTSL EPGTVVITEQ AVDTCFKAEF EQIVLGKRVI RKTDLNKKLV QELLLCSAEL SEFTTVVGNT MCTLDFYEGQ GRLDGALCSY TEKDKQAYLE AAYAAGVRNI EMESSVFAAM CSACGLQAAV VCVTLLNRLE GDQISSPRNV LSEYQQRPQR LVSYFIKKKL SKA 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 : Store it at -20°C to -80°C for one year. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
