Recombinant Protein Expression and Purification in Bacteria and Insect Cells

America Diagnostics offers comprehensive recombinant protein expression and purification services. Our expertise spans various expression systems, ensuring high-quality protein production tailored to your specific needs. Here are our key strengths:

Bacterial Expression Systems:

  • We utilize a T5 promoter coupled with a linear response operator to the inducer. This precise control allows us to adjust protein synthesis rates more tightly.
  • Our broad host range promoter works not only in E. coli, but also in Pseudomonas putida and Bacillus subtilis. This versatility makes it an ideal vector for different host organisms.

Insect Cell Expression:

  • For insect cells, we offer both transient transfection for small-scale tests and large-scale protein expression using the baculovirus system.
  • Our services are reliable, ensuring high-quality protein yields with a guaranteed purity of over 90%.


  • Based in San Diego, California, we are strategically positioned to serve clients with efficient and timely protein expression and purification solutions.
