Product Properties Alternative Names C-reactive protein, CRP, PTX1, MGC88244, pentraxin 1, PTX1MGC149895 Species Cynomolgus Expression Sequence Gln19-Ser224 Accession XP_045255377.1 Tag C-His Expression System HEK293 Molecular Weight The protein has a predicted MW of 24.33 kDa. Due to glycosylation, the protein migrates to 25-30 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 Tris, 150mM NaCl (pH 8.0). 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 ~ -15℃, valid for 1 year after receipt. After reconstitution, store at -85 ~ -65℃ under sterile conditions, valid for 3 months.
