Leadgene Biomedical Inc. - GMP proteins and all-around solution provider for proteomics studies distributed in the UK by Caltag Medsystems

LeadGene Biomedical

Leadgene Biomedical Inc., founded in 2013 in Taiwan, develop and manufacture quality research tools such as proteins, antibodies, ELISA kits, immunoassay kits, and biochemicals.

Their products are used in a wide range of fields, including academic research, drug discovery and development, and diagnostic development.

Leadgene can also provide custom services, including custom antibody production, protein production, and assay development.

GMP-Grade Proteins

Leadgene's GMP-grade proteins are produced in a way that adheres to good manufacturing practices, ensuring they are produced consistently and accurately, and that they meet the required specifications for purity, quality, and safety.

GMP-grade proteins are used as components of cell culture media, or as reagents in the production or purification of cells.

Using GMP-grade proteins can help to minimise the risk of contamination or adverse effects and can help to ensure that the cells used in therapy are of the highest quality.
