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.

General description
Analysis Note
contenuto in solfati - usato come indicatore di purezza, poiché il solfato è il principale gruppo ionico presente.
forza del gel -la forza che deve essere applicata a un gel per provocarne la rottura.
punto di gel - la temperatura alla quale una soluzione acquosa di agarosio gelifica al raffreddamento La transizione dallo stato liquido a gel delle soluzioni di agarosio è soggetto a isteresi, ovvero il punto di gel non coincide con la temperatura di fusione.
Elettroendosmosi (EEO) - indica un movimento di liquido attraverso il gel. I gruppi anionici in un gel di agarosio sono fissati alla matrice e non possono muoversi, mentre i controcationi dissociabili possono migrare verso il catodo nella matrice, dando origine a EEO. Poiché il movimento elettroforetico dei biopolimeri è solitamente diretto verso l'anodo, l'EEO può disturbarne la migrazione a causa della convezione interna.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 risposta-
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

Is this agarose high-resolution, and suitable for PCR applications?
1 risposta-
The High Resolution Agarose, product number A4718, is an intermediate-melting agarose that offers approximately double the resolution capability compared to standard agarose. It is capable of resolving PCR products and DNA fragments ranging from 200-800 bp that differ in size by as little as 2%. This makes it ideal for separating small DNA fragments, such as PCR products, with very small size differences, offering a resolution comparable to that achieved with polyacrylamide gels.
