Preparation Note
Recombinant, human TGF-β 1 exerts its biological activity in the concentration range of 0.01–10 ng/ml.
Working solution: Dilute the concentrated TGF-β1 solution (1 μg/ml) with PBS or culture medium containing BSA [or HSA (human serum albumin)], 1 mg/ml (0.1%) or serum 1–10%.
Storage conditions (working solution): For best results, prepare appropriate aliquots and store at -15 to -25 °C.
