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
Application
- to form the photosynthetic slab
- in comparative study, to compare it with native agar, and agarose of Gracilaria dura
- to estimate the amino acid concentrations in agarose and agar samples
- as immobilisation substrates for enzyme immobilisation
- for separating high molecular weight nucleic acids at low gel concentrations
Biochem/physiol Actions
Analysis Note
Contenido de sulfatos - utilizados como un indicador de pureza, ya que los sulfatos constituyen el principal grupo iónico presente.
Fuerza del gel - la fuerza que debe aplicarse a un gel para provocar su fractura.
Punto de gelificación - la temperatura a la cual una disolución acuosa de agarosa forma un gel cuando se enfría. Las disoluciones de agarosa exhiben histéresis en la transición de líquido a gel - es decir, su punto de gelificación no es el mismo que su temperatura de fusión.
Electroendosmosis (EEO) - movimiento de líquido a través del gel. En un gel de agarosa, los grupos aniónicos están pegados a la matriz y no pueden moverse, pero los contra-cationes disociables pueden migrar en la matriz hacia el cátodo, dando lugar a EEO. Dado que el movimiento electroforético de los biopolímeros suele ser en dirección al ánodo, la EEO puede alterar las separaciones debido a la convección interna.

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
