Storage Conditions | The lyophilized powder is stable for a few weeks at room temperature, but best stored at -20°C. Reconstitute with water to a concentration of 50 μg/ml (e.g., 5 μg/100 μl), this will yield a solution of 1 mM citrate buffer pH 3.5 This solution can then be stored at room temperature or at 2-8ºC for 1 month. It is recommended that further dilutions be made into PBS containing 2 mg/ml albumin and stored at -20ºC. Reconstituted human TGF-beta2 should be stored in undiluted aliquots at -20°C for at least 2 months. Avoid repeated freeze/thaw cycles. |
