Product Properties Alternative Names Guanylyl cyclase C, GC-C, STAR, GUCY2C, GUC2C, STA receptor, DIAR6, EC 4.6.1, GCC, GUC2CEC 4.6.1.2, MUCIL Species Mouse Expression Sequence Val20-Met433 Accession Q3UWA6-1 Tag C-His-Avi Expression System HEK293 Molecular Weight The protein has a predicted MW of 50.01 kDa. Due to glycosylation, the protein migrates to 70-120 kDa based on SDS-PAGE result. Purity > 95% as determined by SDS-PAGE and HPLC. Endotoxin < 1.0 EU per μg by the LAL method. Formulation Lyophilized from 0.22μm filtered solution in 20mM PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Appearance Lyophilized Powder Reconstitution Method Before opening, centrifuge briefly. Reconstitute the lyophilized protein with distilled water to a concentration exceeding 100 μg/mL. Aliquot after initial reconstitution to avoid repeated freeze-thaw cycles. Features High purity, high activity, low endotoxin, high batch-to-batch consistency Storage Store at -25 to -15°C. The shelf life is 1 year from the date of receipt. After reconstitution, store at -85 to -65°C under sterile conditions for up to 3 months.
