How to make a RIPA lysis buffer solution Measure out 3 mL sodium chloride (5 M), 5 mL Tris-HCl (1 M, pH 8.0), 1 mL nonidet P-40, 5 mL sodium deoxycholate (10 %), 1 mL SDS (10%) and add to a 100 mL Duran bottle. Top up the Duran bottle to 100 mL with ddH2O. Mix ...
All enzyme storage conditions are validated through our Quality Assurance re-assay program to maximize long term stability. Setting up digests with a single restriction enzyme is relatively straightforward. However, digests using multiple enzymes that have different buffer requirements may demand the use...

B) If you add 2 mL of 1 M NaOH to the solution in part A, what will be the pH? Describe the preparation of a 1.50 M, pH 8.0 tris buffer (500 mL) using tris base (MW = 121.1 g/mol) and 3.0 M HCl. pK_a of tris is 8.3. To make 50 mM Tris buffer pH = 7.8 how many...
Before electrophoresis, the supernatant should be boiled again for 5 minutes to ensure denaturation. Preparation of RIPA Buffer Basic components: Tris-HCl (buffer component to prevent protein denaturation), NaCl (salt component to prevent non-specific protein aggregation), NP-40 (non-ionic detergent ...
with good aeration overnight. Make sure to take a blue colony on an X-gal/IPTG plate. 2)Harvest the cells by centrifugation, and resuspend the cell pellet in Solution I (without lysozyme). Use 25 ml Solution I per liter culture.
The temperature was reduced to 16 °C following induction, and the cells were incubated for another 12–16 h. The bacteria were harvested by centrifugation and resuspended in lysis buffer (50 mm Tris-HCl, pH 8.0, 0.3 M NaCl, 10 mm imidazole, 2 mm MnCl2 and 1 mm DTT), sonicated on ...
Surprisingly, neither of the two FnIII-2 leg modules appear to make contact with the ligand-free (L1′-CR′) + αCT module in the open-leg structure (Figure 7C). As far as can be discerned, the distance (∼80 Å) between the respective C termini of FnIII-3 and FnIII-3′ ...
Which buffer system is the best choice to create a buffer with pH=7.20? For the best system, calculate the ratio of the masses of the buffer components required to make the buffer. HC2H3O2/KC2H3O2 H If you were conducting an experiment with pepsin, which has optimal en...
Answer to: You have a stock solution of 10.0 M NaCl. You want to make 100 mL of a 1.0 M NaCl solution. How would you dilute the stock to create...
