Acrylodan T40978

Product Introduction
Bioactivity


英文名: Acrylodan

描述: Acrylodan, when subjected to thiol reactions, exhibits sensitivity to the dipolarity and dynamics of its surrounding binding pocket, specifically those surrounding Cys 34.

体外活性: Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs). Purification and Labeling of Act1: 1. 20-fold molar excess of acrylodan (Anaspec) was added to the polymerized actin and incubated on ice overnight. 2. The labeled actin is centrifuged (2 h, 4 °C, 100,000 × g) then the pellet was resuspended in 10 mm Tris, pH 7.5, 0.5 mm β-mercaptoethanol, 0.2 mm CaCl2, 50 μm ATP and dialyzed against the same buffer for 70 h at 4 °C. 3. The supernatant was collected and the actin concentration and degree of labeling were calculated using the extinction coefficient 26,600 M ?1 cm ?1 for actin at 290 nm, 18,500 M ?1 cm ?1 or acrylodan at 385 nm, and 71,000 M ?1 cm ?1 for Alexa Fluor 488 at 494 nm. 4. Acrylodan-labeled Act1 ( Acryl Act1 NAT ) is dramatically different than that of EDTA-unfolded Acryl Act1 ( Acryl Act1I3), which has a very similar emission spectrum to CCT-bound Acryl Act1.
