Hi Wendy Ochoa the information you receive from different CROs will vary, but in any case, I urge you to ask for all the specific information you require before you consider purchasing a phage display library from any supplier.
From ProteoGenix, with all of our immune/naïve phage display libraries you always receive:
A detailed list of library components such as quantity, concentration, buffer & storage recommendations: library phages, helper phage, host TG1, primers…
Phagemid information: antibody cloning strategy (restriction sites), detailed sequence of primers & linker (scFv), vector map + detailed sequences upstream and downstream of antibody insert, insertion frequency (%) and in-frame sequence frequency (%), statistical distribution of number of AAs in the CDRs, total library diversity…
Detailed guidelines about how to use library: which materials and how to prepare/get them (like culture media, buffers and plates), biopanning protocol, phage preparation protocol, phage screen protocol…
Our team will be also at your disposal to answer any additional questions.
Please do not hesitate to contact us, we would be happy to assist you in choosing the best solutions for your projects: https://www.proteogenix.science/antibody-production/phage-display-services/
