Protein expression in E.Coli
protocol
This protocol described a strategy of parallel expression of a protein from a variety of vectors containing different tags and/or fusion partners, and a variety of E. coli host strains.
The strategy to expression recombinant protein in e.coli involves two ...

Prepare competent cells with RbCl2 method
protocol
PDF protocol from Marimoto lab at Northwestern University.
The procedure can be used to obtain competent cells with a transformation frequency of 10^6 - 10^7 colonies per microgram of DNA. Conveniently, these cells can be stored for months with relatively ...

E.coli recombinant protein proteolysis
troubleshooting
We've been trying to express a pro-hormone as a GST fusion in E. coli
(DH5-alpha) but seem to be having problems with proteolysis - we think this
may be occuring at double basic sites but are not completely sure.

need help for the transformation
troubleshooting
I want to construct a DNA library with different sequence. First step,
PCR, the template contained random 40mers in the middle and normal
sequence on each end. After the PCR, I could obtain the PCR product
library and I ligated them into the plasmid v ...
Best vector for expressing recombinant antibody fragments?
troubleshooting
Does anyone here express recombinant antibody fragments regularly in
their research? Which vector do you use and do you have to refold? I am
looking for one that gives me the highest yields (I know this depends on
individual sequences as well) and ...
Protocol for making competent E coli
troubleshooting
Does anyone have a quick and simple way of making competent E coli for
transformation (heat shock)? ... ...

Plasmid or phagemid vector(s) holding large insert
troubleshooting
I am looking for plasmid or phagemid vector(s) which can hold 50kb DNA insert. I
appreciate it very much if anybody can send me information about the name of the plasmid and the place I can get it ... ...

Transformation efficiency
troubleshooting
If you are getting low transformation efficiency with chemically competent cells:
There were impurities in the DNA. Remove phenol, protein, detergents, and ethanol, by ethanol precipitation or GlassMAX DNA Isolation Systems. There was excess DNA. Use no mo ...
Glycerol stock longevity
troubleshooting
Does any one have information (data or opinion or personal experience) on
how
long a bacterial glycerol stock is viable @ -80oC? How often to stocks fail
to
regrow? Is is necessary to thaw and revitalize the stock at time intervals?
