Generating antibodies
From OpenWetWare
You are hot in pursuit of an interesting protein but there are no commercial antibodies or they are bad. It's time to think about raising your own antibodies against the protein. It will be a time and money consuming undertaking but once you developed a specific antibody or set of antibodies, you will be in a unique position to generate interesting data.
Early decisions
Type of antibody
- polyclonal (faster to generate, less specific)
- monoclonal (slower to generate, more specific, after initial setup no animals required)
Source organism
- rabbit
- goat
- mouse,..
Depends on choice of antibody (monoclonal requires mouse) and antibodies to be used in conjunction with antibody to be generated.
Type of antigen to use
- full-length protein (natural selection of epitope, epitope location initially unknown, may not be availalbe, epitope may not be specific to protein)
- peptide (cheaper, can typically be synthesised without problems, known epitope, possibly low antigenicity)
