Immunoassay and Antibody Purification

At LSI Medience, we have extensive experience of antibody purification and development of immunoassay (RIA and ELISA). We offer TK/PK of biopharmaceuticals such as peptides and antibody pharmaceuticals.
We have expertise in various biomarker assays and contribute to clarifying toxicity and effectiveness of drugs.

In addition, we can prepare monoclonal and polyclonal antibodies (containing purification of antibodies and labeled antibodies).
We also have experience in areas requiring advanced knowledge and technology, such as development of measurement systems using antibodies.
Affinity analysis of antibodies using Biacore as well as quantification of antibodies against biopharmaceuticals etc. are also carried out at LSIM. Please do not hesitate to contact us.
