2017年11月13日 — Mix 1 - 5 μl of DNA (usually 10 pg - 100 ng) into 20-50 μL of competent cells in a microcentrifuge or falcon tube. GENTLY mix by flicking the ...

Plug the data into the above equation to determine the number of transformants per microgram of DNA. Transformation efficiency generally ranges from 1 x 104 to ...

Use no more than 1-10 ng of DNA in 5 µl for a 100 µl reaction or in 1-3 µl for a 50 µl reaction. Low ligation efficiency. Vector insert ratio not optimal. Use a ...

由 JDM Tripp 著作 · 2013 · 被引用 39 次 — Transformation efficiencies using the optimized protocol were typically ~50,000 – 100,000 per µg DNA, depending on the yeast strain employed, ...

The optimal amount of DNA is lower than commonly recognized. Using clean, supercoiled pUC19, the efficiency of transformation is highest in the 100 pg-1 ng ...

The volume of DNA to be added into competent cells does affect transformation efficiency. 1-5 µl of DNA (plasmid or ligation product) is recommended for 50 µl ...
