Lab work: Sriram & Orr

Prepared 1 litre of LB agar medium and sent to Kluyver lab's kitchen.

Using 650 ul of competent cells (E.coli DH5alpha) and the transformation protocol, we inserted 13 biobricks for delay into those competent cells and grew them in a solid media to increase the amount of biobricks we will have.

Diluted the 13 biobricks with 15 ul RNase free water and stored in -20°C freezer.

Standard transformation procedure:

Remove competent cells from -80, let thaw for 10 min on ice and aliquot in 50 ul amounts.
add 2-5 ul of vector, usually in H2O, to 50 ul cells, no mixing by pipet due to shear induction.
keep on ice for 20 minutes (vector spreading through volume).
heat shock (42°C) for 45 seconds.
keep on ice for 2 minutes.
add 200 ul SOC, put on 37°C for 1 hour or longer with agitation (160 rpm).
plate out 250 ul on appropriate antibiotics.
