What are Recombinant Proteins Used for in Research?

Recombinant proteins are engineered in common expression systems – including E. coli, HEK293, or CHO cells – to provide a consistent source of functional proteins for experimental use. They are critical tools in:

Cell signalling and receptor studies
Functional assays
Drug screening and target validation
Protein-protein interaction analysis
Vaccine development
Cell proliferation and differentiation
Diagnostic assay development

Using purified, validated recombinant proteins helps to ensure reproducibility, reliability, and meaningful biological outcomes.

Protein FAQs

How quickly will my proteins be delivered?
Most proteins can be shipped within 7-11 business days with door-to-door delivery worldwide. On average, packages are delivered overnight within the US and Canada, and in 3-4 business days to Europe and most other countries.

What is the purity of Biomatik proteins?
Most of our proteins are purified to ≥90 % using affinity or size-exclusion chromatography. Purity levels are provided on each individual product datasheet.

Which expression systems do you use?
We use various expression systems – including E. coli, HEK293, and CHO cells – depending on the protein's complexity and required post-translational modifications.

Are your protein reagents biologically active?
Yes. Where relevant, proteins are supplied in their active form and tested in functional assays. Specific activity data is included in the product documentation.

Do you offer bulk or large-scale protein supply?
Absolutely. Many proteins are available in bulk quantities, suitable for assay development, production-scale research, and more. Please contact us for more information.

Can I request a custom protein or peptide?
Yes, we offer both custom protein production and peptide synthesis services for bespoke targets and formats.
