Q&A and Customer Reviews


We have recently transfected MDR1 gene in some cell line and I would like to Quantify the level of MDR1 in transfected cell line vs. Wild type cells
would you please suggest whether your product#CSB-E11709h will be ok for this purpose or not?

Thanks for your inquiry.
If you want to analyze the the level of MDR1 in transfected cell line vs. wild type cells,it is workable theoretically to use our kit#CSB-E11709h .But it is associated with the type of cells and the whole experiment system ( especially with the operations during the transfection and expression efficiency.Additionally,as MDR1 is membranin,we suggest you do pre-testing first.Pls let me know if you have any further questions. Thank you.
