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.

Application
- Calibration of the polymer-based column in the estimation of molecular weight of the polysaccharide fractions obtained from seaweeds— S. latissima and M. stellatus, by a high-performance size exclusion chromatography (HPSEC) method
- Measurement of molecular masses of oligomeric cellulose by size exclusion chromatography in combination with multi-angle laser light scattering (MALLS) detection
- To calibrate the SEC column in the determination of molecular size distribution of microalgal native glycogen
- Quantitative analysis of membrane formation process of alginate–chitosan microcapsules using gel permeation chromatography(GPC).[1]

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

What is specification for GPC pullulan standards. Pullulan standard with Mp 22000Da supplied in different lot can vary how much % from 22000Da
1 answer-
This product is intended for use as a calibration standard for GPC/SEC/GFC systems. While there is not specification for the Mp values, these are reported on the lot specific Certificate of Analysis. The lowest value reported for the Mp 220000Da is 19.4000Da. Please see the link below to review a sample or lot specific Certificate:
