FAQs
Do you offer bulk discounts?
Yes. You may be eligible for a discount when placing a bulk order. Please contact us to request a quotation before placing your order. Catalog prices are already 10% below comparable public list pricing.
Can you isotopically label a protein I already purified?
We cannot isotopically label purified proteins that you provide. Isotope labeling must occur as the protein is produced, when we supply an N15 nitrogen source or C13 carbon source. For FITC or dye labeling, contact custom services.
Are lots consistent?
Our recombinant products are manufactured for batch-to-batch consistency in physical and chemical properties. Always archive lot numbers from your Certificate of Analysis.
Where can I find publications?
See the Citations resource page for themes and contact sales for product-specific references.
Are products for human use?
No. Products are for research purposes only — not for human consumption, cosmetic, or medicinal use.
