Preguntas frecuentes
What should I compare when selecting Native Proteins?
Within Native Proteins, compare source and expression system, purity and the method used to measure it, specific activity, and buffer composition. In a sensitive assay the buffer can matter as much as the protein itself.
Which Native Proteins subcategory should I start with?
Native Proteins is organised into Human Proteins, Bovine Proteins, Mouse Proteins, Immunoglobulin proteins and Complement Proteins, and 1 further subcategories. Choose by the workflow step you are at rather than by molecule type — most workflows draw from more than one subcategory.
Which quality data should I review before ordering Native Proteins?
Review the lot-specific Certificate of Analysis for the Native Proteins product — purity, activity, and endotoxin — and confirm the buffer and any carrier protein. Carrier-free formats are worth specifying where downstream labelling or conjugation is planned. All products are supplied for professional research and development use only, and are not for use in humans, animals, diagnostics, or therapy.
What documentation is available for Native Proteins?
Each Native Proteins product page links a datasheet and a lot-specific Certificate of Analysis covering purity, activity, and storage. For lot reservations, bulk quantities, or documentation not shown, contact [email protected].
