Descrição geral

Biotin is a water-soluble vitamin. Mammals depend on biotin via plant and microbial dietary sources.[1] Biotin consists of two rings that are attached to valeric acid moiety as a side chain. One of the rings is attached to ureido group and the other ring is the tetrahydrothiophene group.[2]

Aplicação

Biotin may be used to elute proteins from avidin/streptavidin resins. Biotin has been used:
  • for culturing of oligodendrocytes.[3][4]
  • as a vitamin supplement for the growth of Bacillus species.[5]
  • for blocking endogenous biotin during immunohistology procedures.[6][7]

Ações bioquímicas/fisiológicas

Biotin is a small molecule and its presence with biologically active macromolecules does not affect the biological function of the macromolecule. The biotin-(strept)avidin system are is required for various applications. Biotin also works as a cofactor/coenzyme of carboxylating enzymes, such as pyruvate carboxylase, acetyl-CoA carboxylases 1 and 2, 3-methylcrotonyl-CoA carboxylase (MCC), and propionyl-CoA carboxylase (PCC).[1] It catalyzes the formation of oxaloacetate from pyruvate and CO2. Biotin conjugation with avidin or streptavidin helps in linking the target molecule (antibody, nucleotide, protein A, etc.) with the labeling system (enzyme, fluorescent, chemiluminescent probes). This complex is used for many detection systems, such as immunoassays, DNA hybridization assays, immunohistochemistry, and flow cytometry. This approach is also applied for to the purification and characterization of various molecules of interest. Biotin is involved in the epigenetic regulation of genes, cell signaling, and the structure of chromatin.[1]

Exercise induces a marked increase in interleukin-8 (IL-8) mRNA and protein expression within skeletal muscle fibres. Interleukin-8 belongs to a subfamily of CXC chemokines containing a Glu-Leu-Arg (ELR) motif. CXC chemokines with ELR motifs are potent angiogenic factors in vivo

The cytokine interleukin-15 (IL-15) has been demonstrated to have anabolic effects in cell culture systems. We tested the hypothesis that IL-15 is predominantly expressed by type 2 skeletal muscle fibres, and that resistance exercise regulates IL-15 expression in muscle. Triceps

Questions

1–3 of 3 Questions  
  1. 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.

  2. 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
