If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

How are the detection range and sensitivity determined for the MAK057 assay?
1 answer-
The calculation of the higher limit of detection is determined by dividing the highest concentration of the standard by the minimum sample volume. Similarly, the lower limit of detection is calculated by dividing the lowest concentration standard by the maximum sample volume. In the event that a sample exceeds the range of the standard curve, it is advisable to conduct a dilution and then adjust for the dilution factor.
For instance, for the MAK057 test:Colorimetric:
• Lower range: 2 nmol/50 = 0.04 mM or 40 uM
• Higher range: 10 nmol/1 uL = 10 mM or 10,000 uM
Fluorometric:
• Lower range: 0.2 nmol/50 = 0.004 mM or 4 uM
• Higher range: 1 nmole/1 uL = 1 mM or 1000 uMHelpful?
