Product Overview
Fusion BioLabs offers a range of library primer sets and phagemid vector combination for antibody phage display and peptide phage display construction. With customizable features and robust performance, our primer sets and phagemid vectors are designed for facilitating phage display library generation as fast as within one week.
pAPD-m-scFv is the phagemid vector for construction of a single-chain variable fragment (scFv) library for mouse antibodies. Here are the key steps involved in constructing such a library:
- Amplify V genes from cDNA reverse transcript from RNA isolated from peripheral blood lymphocytes (PBL) or lymphoid tissue of non-immunized or immunized donors using PCR primers corresponding to known VH, Vκ, and Vλ gene sequences.
- Combine VH and VL repertoires to create the scFv construct using a simple two-fragment PCR assembly procedure.
- Restriction enzyme digestion with SacI/SpeI
- Ligation of digested and purified scFv fragment into corresponding restriction enzymes(s) digested and purified pAPD-m-scFv
Key Features
High expression efficiency: Engineered for efficient expression and display of antibody fragment scFv on the surface, allowing for easy screening and selection of target molecules.
Flexibility and versatility: One vector for both antibody library construction and downstream antibody fragment expression. No need subcloning into expression vector for downstream application.
