WebbApproximately 90 µg of mouse GATA2 sgRNA (IDT) was digested using 24 µg (~10 kU) of guanosine-specific ribonuclease T1 (Worthington Biochemical Corporation, Lakewood, NJ). First, the RNA was denatured with 20 µL of 8 M urea prepared in nuclease-free buffer (10 mM Tris-HCl pH 7.5, 0.1 mM EDTA) at 80 °C for five minutes. WebbHerein, we report a facile, efficient and versatile method for the photo-regulation of pH-dependent activities of artificial enzymes by incorporating flash photolysis reagents. Under light excitation, a persistent pH shift is achieved by proton release from photosensitive 2-nitrobenzaldehyde. Following such

Webb22 maj 2024 · There is an interesting study showing that antibodies can be used up to 26 years past their expiration dates. I also had a colleague who used only expired enzymatic solution for tissue digestion as she found it to be less harsh on cells. The answer, in my opinion, regarding the use of expired reagents is risk-managing.
