Do not add "and" when entering multiple search terms.
Use the singular (e.g. "antibody" instead of "antibodies").
If available, try synonyms (e.g. for a specific protein).
You can search for chemical substances using the unique CAS number (Chemical Abstracts Service).
In addition, you can also use the UniProt or KEGG accession number for the product search.
Use our filter function to narrow down your search results. If you want to remove a selected filter again, click on the small "x" next to the filter.
Are you looking for products from a specific supplier? Then enter the corresponding supplier name and select it in the appearing suggestion field. Alternatively, you can also use our supplier overview.
Use - if known - the specific product number. Especially for short numbers, note the supplier code in front of each number for most of our partners (e.g. for AAT Bioquest "ABD-121" instead of just "121"). Click on the button below to find all supplier codes and additional information.
