OverviewPerforming Type IIS assembly on the amplified, BsmBI-tagged parts. These are the parts I currently have:
All parts are located in the "Ben's luc replacement" box on the second shelf in the large -20 °C freezer. Parts are taped together. Overview of assembly can be found on Benchling: https://benchling.com/s/sICuMhHj/edit
Gel Extraction of HPK:CFP fragmentPerform standard gel extraction on the HPK:CFP fragment in the PCR tube. Use the entire tube contents (~45 µL) to maximize yield, if possible. The band you are aiming to extract is 2000 bp in size. It will probably be the smaller of two main bands - the larger one is ~1500 bp in size. Quantify on the plate reader. Type IIS AssemblyWe want a 2:1 molar ratio of inserts to vector, and will be using 75 ng of vector total for this reaction. Therefore the required volumes from the parts are:
Calculating volume of insert required: 2*(insert size in bp / vector size in bp) * 75 ng / insert concentration in ng/µL Set up the reaction as follows:
Thermal cycler program:
Bacterial TransformationFollow the steps for traditional transformation of chemically competent cells with ligation product. Use entire reaction volume to transform. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
