Double Digestion and Cleanup of pET24a

  • Sequencing results checked out for miniprepped pet 24a plasmid.
  • I will be using the first sample from 7/9 (OD: 231.26ng/uL)

Digestion Reaction

Component Volume (out of 50uL)
NEB 2.1 Buffer 5uL
BamHI 1uL
NdeI 1uL
pET24a (Miniprepped) 5uL
Nuclease Free Water 38uL

Program

Step Temperature Time
Incubation 37C 1 hour
Heat Inactivation 80C 15 min
Hold 10C Hold

I ran the sample on a 1% agarose gel against a 1kB ladder. The appropriate band length was present (5310 bp).

(picture, do this asap)

The band was excised from the gel and purified along with the collected gel sample of the honeybee insert from 7/8 using the Qiagen Gel Purification kit.

OD: Honeybee silk: 28.4ng/uL pET24a: 23.6
