Certificate of Analysis

Certificate of Origin

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page. You can contact any of our Customer Sales and Service offices to receive a quote.  USA customers:  1-800-325-3010 or view local office numbers.

  4. Which filter sets can be used to visualize the fluorophore produced by Product D9564, DAPI, dilactate (DAPI-DNA)?

    One such filter set is the Zeiss Filter Set 01 (ex=359 nm, em=461 nm), information about which is posted here.

  5. Isn't the hydrochloride salt form of DAPI a more sensitive detector of DNA than Product D9564, DAPI, dilactate (DAPI-DNA)?

    The dilactate salt has as much sensitivity in detection as the dihydrochloride salt, which we also offer as Product No. D9542.

  6. Can Product D9564, DAPI dilactate (DAPI-DNA), be used as a vital stain?

    As we note in the Product Information Sheet for the Dihydrochloride salt of DAPI, Product No. D9542, DAPI can be used as a vital dye to stain mature pollen grains, but we have tested it as a vital stain in other cell types.

  7. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product.

Multidrug resistance (MDR) is a major impediment to curative cancer chemotherapy. The ATP-Binding Cassette transporters ABCG2, ABCB1 and ABCC2 form a unique defense network against multiple structurally and functionally distinct chemotherapeutics, thereby resulting in MDR. Thus, deciphering novel mechanisms of...
