Week #4 27th September - 01 October 2010

Monday

Well we are stuck with the vector this week we have to get vector is our main objetive.

  • We have achived a nanodrop readings as below


ng/μl 260/280 260/230
PsB1C3 0.60 -0.73 -0.0
PCR 1 red 427.70 1.71 1.71
PCR 2 red 483.20 1.74 1.71
PCR 3 red 410.70 1.76 2.02
PCR 4 red 431.05 1.61 1.88
PCR 1 blue 533.35 1.71 1.75
PCR 2 blue 536.00 1.72 1.82
PCR 3 blue 577.50 1.69 1.59
PCR 4 blue 627.55 1.70 1.56
PsB1C3 4.10 2.62 1.01


  • Yep our trouble is the lisis alcaline method to do the mini prep

we have a low concentration of vector’s plasmid DNA.

We have to work an try to get more plasmid and make dilutions of PCR’s

is not posible to do ligations with this ratio betwen vector an insert.

On this step we advisor has proposed a method via Low Meelting agarose

to geting out plasmid from the band.


Tuesday

We run with a low meelting's agarose prove to extract band tomorrow

we do a protocol to precipit with alchol an salts our objetive is do it all

to get vector and do the ligations.

Wensday

We prepared all to do ligations PsB1C3 with our Pcr's

for this we going to cut with EcoRI and PstI both vector and insert

We run a low melting gel slow 2 hours and a half then purified from the band
