Help: Confused with primers in a PCR of a vector?

... being introduced to a lot of different lab techniques, so I'm not entirely familiar with what is going on. We recently ligated a gene into a pBS vector and popped it into some E. coli cells. We looked for positive clones via blue/white screening and isolated/purified the respective plasmid. Then, ...

Re: Gene cloning question

... sequence is CA/TATG, My question, is The ATG of Nde1 act as a start codon in result I must delete The ATG of my sequence or I can use the ATG of vector in Nde1 site as a start codon? (NOTE: My gene is eukaryotic) Is there anyone make a sugestion?

Re: Cell and Molecular Revision Question Help!!!

This is what I have.. Consider the Vector (Mass of Vector): pBR328 (4.9 x 103) x 660 = 2.94x106 Daltons Given: Moles = Mass/MW Moles = 50 x 10-9g / 2.94x106 Moles = 17 x10-15 Each vector has two ends therefore x2 = x2 Therefore there are 34 ...

Cell and Molecular Revision Question Help!!! (2)

... insertions using blue/white selection. Given that there are 50 nanograms of EcoRI digested pBR328, on the basis of the optimal ratio of insert: vector for ligations, how much insert would be added to the 50ng of EcoRI digested pBR328 to ensure the best possible chance of successful ligation? ...
