Lentivirus, shRNA plasmid, or siRNA? Choosing between Lentivirus (somewhat stable), shRNA transfer vector (stable/transient), or siRNA (transient). Perform and exhaustive literature search (pubmed) for citations that have reported RNA/DNA delivery...

Engineering BioBrick vectors from BioBrick parts/Restriction digest-PDF

Materials Restriction enzymes (EcoRI, SpeI, XbaI or PstI) from NEB Bovine Serum Albumin (BSA) Deionized, sterile H2O 0.5-1 μg DNA Sterile 0.6mL plastic tubes Equipment ...

PNK Treatment of DNA Ends-PDF

Introduction This protocol is used to add a phosphate group to the 5' end of a single or double stranded DNA molecule. Most primers, for...

Phosphatase treatment of linearized vector-PDF

To minimize self-ligated vector in your transformation, treat your linearized vector with a phosphatase to remove the 5' phosphates necessary for ligation. This should...

Round-the-horn site-directed mutagenesis-PDF

Background I was in graduate school and had to make several codon substitutions at the same position in a cloned gene. I came up with...

Site-directed mutagenesis-PDF

General Information Site-directed mutagenesis can be used to change particular base pairs in a piece of DNA. There are several methods for achieving this. The...

Cloning Protocol-PDF

PCR There are two types of PCR polymerases used in the lab, TAQ and Phusion. Phusion is more accurate, having fewer mutations or errors in...

Site-directed mutagenesis/Multi site-PDF

Materials Template plasmid purified from a dam+ E. coli strain (not JM110 or SCS110) Mutagenesis primers (one permutation, each on the same strand) PfuTurbo...

Stitching Genes by PCR-PDF

Introduction This method allows you to "stitch" genes or coding sequences together when there are no convenient restriction sites at the junction point. It is...
