Antibodies

The Challenge A client asked us to generate Fab and Fc pools from a full-length antibody using Papain digestion. In this case study, Camila Torres, one of our protein scientists describes the issues that we encountered and the conclusion we came to for tackling [...]

A client recently requested the production of two bispecific antibodies and provided us with the heavy and light chain variable sequences that they required. After reviewing the literature, we decided to produce these bispecific antibodies as fused, single-chain variable fragments (scFvs) with an N-terminal [...]

We had been asked by a client to express and purify a protein:Fab complex to support a Cryo-EM project. This was just to be a reproduction of a crystal structure that had been reported in the literature and so on the face of it [...]

As a leading protein purification company, BiVictriX required us to develop a method to purify 10mg each of 24 different antibody-binding fragments (Fabs) to be tested in assays. Once analysed by BiVictriX, a smaller number of chosen constructs were to be scaled up by [...]
