1) What is the purpose of using Lyse blue reagent for DNA extraction?
2) What is Inoue's transformation buffer and its role in making competent cells?
Ans 1)
LyseBlue is a colour indicator which provides visual identification of optimum buffer mixing. It can be added to the resuspension buffer (P1) bottle before use. Also, very less amount of LyseBlue can be added to Buffer P1, enabling single plasmid preparations having visual lysis control to be performed.The reagent allows the user to monitor potential problems early in the plasmid preparation procedure.

Principle of blue- white screening method(why do the colonies appear blue or white? what do we try to recover?what are the roles of substrate (Xgal) and the gene expression inducer(IPTG)?) this experiment was GENETIC DEFECT CORRECTION WITH BACTERIAL TRANSFORMATION In this experiment we did that first of all,1 µl of plasmid DNA was added into the tube which contains competent cells and the tube was tapped gently to mix DNA and the competent bacteria.After that it was placed on ice...
