Frequently Asked Questions
How do I choose the right Primary Antibodies product for my experiment?
Match the Primary Antibodies product to the application first — Western blot, ELISA, cell-based assay, and structural work make different demands. Then check species reactivity or source organism, format (lyophilised or solution), and whether you need an activity-verified lot.
What does the Primary Antibodies category include?
Primary Antibodies covers Flow Cytometry Antibodies, Loading controls, Tags Antibodies, Therapeutic Antibodies and Cell Marker Antibodies, and 8 further subcategories. Each product page lists format, purity, and storage so items from different subcategories can be compared on the same terms.
What specifications matter most for Primary Antibodies?
For Primary Antibodies, check purity by SDS-PAGE or HPLC, endotoxin level for cell-based work, specific activity, tag and expression system, and the reconstitution and storage conditions. Repeated freeze-thaw is the commonest cause of lost activity. All products are supplied for professional research and development use only, and are not for use in humans, animals, diagnostics, or therapy.
Can I search Primary Antibodies by target, species, or application?
Yes — filter Primary Antibodies by application, species reactivity or source, and format, and search by gene or protein name. For items not listed, contact [email protected]. We supply verified businesses, research institutions, universities, and government agencies.
