| Product Name: | TVMV C4 Protease |
| Catalog #: | RP-0165 |
| Manufacture: | LD Biopharma, Inc. |
| Intruduction: | TVMV protease derived from Tobacco Vein Mottling Virus, recognizes a linear epitope of the general form T_V_R_F_Q / S with cleavage occurring between Q and S. The protease is used to cleave affinity tag from fusion protein. The optimal temperature for cleavage is 30 °C. TVMV protease could be easily removed from the cleavage reaction by affinity chromatography using the polyhistidine tag at N-terminal of the TVMV C4 enzyme. |

| Applications: | Typical Reaction Condition The "standard" reaction buffer for TVMV C4 protease is 50 mM Tris-HCl (pH 8.0), 0.5 mM EDTA and 1mM DTT. The duration of the cleavage reaction is typically overnight, although lots of cleavage will happen in the first few hours and prolonged incubation times may not lead to proportional increases in cleavage. TVMV C4 protease is maximally active at 34 °C, but we recommend performing the digest at room temperature (20 °C) or 4 °C overnight. Typically, a good rule of thumb for initial test of digestion is 1 ug C4 enzyme per 50 – 100 ug target protein ratio. Perform a small-scale reaction first, if possible, to gauge the efficiency of processing. |
| Quality Control: | 1. Purity: > 95% by SDS-PAGE. 2. Activity: Completely digestion 50ug of MBP-IL6 fusion protein using 1 ug C4 enzyme (in 1 : 50 ratio) for 12 hours at 4C. |
