Why Our In-Stock Collection Makes a Difference?

In research, time matters. You don’t always have the luxury to wait weeks for essential reagents. That’s why we’ve put together this collection of in-stock recombinant proteins—so you can get what you need, when you need it.

Whether you're involved in biomedical research, therapeutic development, diagnostics, or cell signaling studies, we’ve got proteins that meet your needs and ship right away.

All proteins in this collection are produced using trusted expression systems like E. coli, mammalian cells, insect cells, and yeast. This ensures high bioactivity and proper folding, so your experiments get reliable results every time.

They are carefully purified, checked for activity, and tested for consistency. Whether you're running one test or working with large sample sizes, you’ll get the same quality in every batch.

Key Features You Can Count On

✔ High purity & strong bioactivity: Each protein is tested to ensure it performs well in real experiments
✔ Research-ready: Ideal for biomedical research, diagnostics, drug development, and more
✔ Multiple expression systems: E. coli, mammalian, insect, or yeast-based proteins, depending on your needs
✔ Lot-to-lot consistency: You get the same quality in every order, which helps reduce variation in your results
✔ Fast & secure delivery: In-stock items ship quickly, with overnight options available in the U.S.
