Can anyone please guide me through how to design crRNA for Cas12a based detectioin.
For IVT purpose where should be the T7 promoter and where I should add repeats.

please refer to this website to see the detail of crRNA design.
I have carried out MFC experiments on three different volumes, 50, 500 and 1000 mL of wastewater. Results after MFC treatment shows that TDS and EC are more in larger volumes of water i.e. TDS and...

I only have used sgRNAs. For the first time I used crRNA+tracrRNA and I kept what was left in the -20C. Can I use it again or is it better to prepare fresh crRNA+tracrRNA? Thank you :)
