Descripción general

La estreptomicina activada (SA) y la peroxidasa de rábano picante (HRP) están conjugadas covalentemente a un esqueleto polimérico. Múltiples biomoléculas activas en cada cadena de polímero aumentan la capacidad de unión a la biotina y amplifican la señal de la enzima peroxidasa.

Especificidad

Biomoléculas biotiniladas.

Aplicación

Detección de proteínas biotiniladas y ácidos nucleicos y otras biomoléculas.
Uso idóneo en la inmunotransferencia Western y el ELISA, y para la detección de antígenos de superficie en inmunohistoquímica e inmunocitoquímica.

Forma física

Se suministra como una disolución 1,0 mg/ml en fosfato sódico 0,01 M, cloruro sódico 0,15 M, glicerol al 50%, estabilizador y conservante, a pH 7,4.

The hypoxia-inducible factor (HIF) activates transcription via binding to the highly variable hypoxia-responsive elements (HREs). All hypoxia-inducible constructs described to date utilize multimers of naturally occurring HREs. Here, we describe the rational design of minimal hypoxia-inducible enhancers, conceptually equivalent to

Questions

1–3 of 3 Questions  

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

    1 answer

    1. 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

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  3. Hi, regarding S2438 is there any information on the length of the polymer and how many HRP and streptavidin molecules each polymer contains?

    1 answer

    1. Unfortunately, the length of the polymer and the number of peroxidase and streptavidin molecules are not determined.
