Product Properties Alternative Names FSH alpha & FSH beta,FSH alphaβFSH alpha,beta Species Human Expression Sequence Ala25-Ser116 (FSH alpha) & Asn19-Glu129 (FSH beta) Accession P0 1215(FSH alpha)&P01225 (FSH beta) Tag C-hFc Expression System HEK293 Molecular Weight The protein has a predicted MW of 10.20 kDa (FSH alpha) and 39.2 kDa (FSH beta). Due to glycosylation, the protein migrates to 25-30 kDa (FSH alpha) and 50-60 kDa (FSH beta) 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 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Appearance Lyophilized Powder Reconstitution Method 1. Centrifuge before opening2. Reconstitute with distilled water (>100 μg/mL)3. Aliquot to avoid freeze-thaw cycles Features High purity, high activity, low endotoxin, high batch-to-batch consistency Storage Lyophilized powder: Store at -25 to -15°C; stable for 1 year upon receipt.
