簡 介:蛋白質(zhì)交聯(lián)劑是一類小分子化合物,具有2個或者更多的針對特殊基團(-NH2、-COOH、-HS等)的反應(yīng)性末端,可以和2個或者更多的分子分別偶聯(lián),從而使這些分子結(jié)合在一起,終形成共軛蛋白。
1. Dissolve protein at a concentration of 1 – 10 mg/mL in 100 mM sodium phosphate buffer, pH 7.0- 8.0. Avoid amine containing buffers, such as Tris, glycine, or imidazole, etc.
2. Create a 50 mg/mL Sulfo-NHS-Acetate stock solution in buffer (same buffer as in step one).
3. To the protein solution, add 2 μL of the Sulfo-NHS-Acetate stock for every mg of protein dissolved. (ie. 10mg of protein = 5 μL Sulfo-NHS-Acetate stock). Note: Alternatively, you can add an equivalent amount of Sulfo-NHS-Acetate to the protein solution (mg of protein = mg of Sulfo-NHS-Acetate).
4. Allow this reaction to proceed for 1-2 hours at room temperature. (2-3 hours if protein stability issues require 4°C incubation).
5. If desired, residual Sulfo-NHS-Acetate can be deactivated by adding 0.5M Tris-HCl, pH 7.4 – 8.0 or 0.5M glycine to this reaction mixture. This is redundant if removing Sulfo-NHS-Acetate by desalting (see step 6).
6. Desalt sample to remove residual Sulfo-NHS-Acetate and reaction bi-products (i.e. gel filtration, dialysis, etc.). Note: As a general rule for amine blocking with Sulfo-NHS-Acetate, 10-50 molar excess of SulfoNHS-Acetate to amines to be blocked will provide sufficient coverage.
