Recombinant proteins are proteins produced using recombinant DNA or RNA technology in host cells. Compared to proteins extracted from natural sources, recombinant proteins have a wider range of sources, higher yields, and more controlled quality, making them play a crucial role in life science research. They are applied in many fields, such as cell culture, activity assays, exploration of protein structure and function, immunology research, drug development, cell therapy, virology research, enzyme studies, etc.
TargetMol currently offers over 13,000 recombinant protein products, covering multiple categories including cytokines, growth factors, receptor proteins, enzymes, and viral proteins. Multiple expression systems can be selected, including prokaryotic systems, mammalian cells, yeast, and insects, etc. We also provide a variety of species options and tag choices. Our products are supplied in solid/dry form to ensure protein stability.

Various expression systems: E. coli expression, yeast expression, mammalian cell expression, insect-baculovirus expression, cell-free expression, VLP platform expression, etc.
Selective tags: Tag Free、His、Flag、Avi、Myc、HA、SUMO、T7、Fc、GST, etc.
High quality: Tests for biological activity, binding affinity ahd enzyme activity to ensure activity requirements; SDS-PAGE and HPLC are validated to ensure high purity.
Low Endotoxin: tested by LAL assay. Most products have endotoxin levels lower than 1 EU/μg and some below 0.01 EU/μg.
High Stability: High stability across batches guarantees experimental reproducibility.
Carrier-Free: Buffer systems do not contain bovine serum albumin (BSA).
Validation
1. High purity
The purity of Human IL-1 beta Protein (TMPY-01049) was >95% determined by SDS-PAGE and >95% determined by SEC-HPLC.
2. High bioactivity
The activity of Human TNF alpha Protein (TMPY-00936) was measured in a cytotoxicity assay using L929 mouse fibrosarcoma cells in the presence of the metabolic inhibitor actinomycin D. The ED50 for this effect is typically 3-30 pg/mL.
