Description générale

The branched-chain amino acids (BCAA), leucine, isoleucine, and valine, are the most common essential amino acids in proteins. The BCAA may function in both energy production and as nutrient signals.[1] Dietary supplementation with BCAA may aid in the treatment of various disorders such as Amyotrophic Lateral Sclerosis (ALS), latent and chronic hepatic encephalopathies,[2] and to prevent muscle atrophy in cancer patients. BCAA may increase the rate of protein synthesis and sensitize cells to insulin and insulin-like growth factor.[3]

Application

Branched Chain Amino Acid Kit has been used to determine the concentration of hepatic branched-chain amino acids, in a study assessing the role of CREB regulated transcription coactivator 2 (CRTC2) in hepatic lipid homeostasis and obesity in mice.[4]

Adéquation

Suitable for measuring Branched Chain Amino Acids (BCAA′s) in a variety of biological samples.

Principe

In this assay, BCAA concentration is determined using a coupled enzyme reaction, which results in a colorimetric (450 nm) product, proportional to the BCAA present. The BCAA Assay Kit provides a simple convenient means of measuring the BCAAs in a variety of biological samples.

Questions

1–2 sur 2 questions  

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

    1 réponse

    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 réponse

    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.
