Product Description
| MW (kDa) | 13 |
| Purity | >98% as determined by SDS-PAGE of 6 μg reduced (+) and non-reduced (-) recombinant hTGF-β1. Less than 1% migrates as monomer hTGF-β1 under non-reduced (-) conditions. All lots are greater than 98% pure. |
| Endotoxin | Less than 0.01 ng endotoxin/1 μg hTGF-β1. |
| Activity | The bioactivity of recombinant hTGF-β1 was determined by assessing inhibition of IL-4 induced HT-2 cell proliferation. The ED50 of each lot is between 40-800 pg/ml. |
| Molecular Formula | Recombinant hTGF-β1 contains no "tags" and the nonglycosylated protein has a calculated MW of 12,794. DTT-reduced protein migrates as a 13 kDa polypeptide and the non-reduced cystine-linked homodimer migrates as a 25 kDa protein. The expected amino-terminal ALDTN of recombinant hTGF-β1 was verified by amino acid sequencing. |
