Vitaminas

<p>Applications A Vitamin D derivative.<br> Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package<br>References Koeffler, M.R., et al.: Blood, 74, 82 (1989),<br></p>

<p>Stability Moisture Sensitive<br>Applications Succinimidyl-6-(biotinamido) Hexanoate is a biotinylation reagent incorporating an aminocaproyl “spacer”. This can reduce the steric hindrance in binding avidin to some biotinylated compounds when used to biotinylate both the antibody and the carrier in the Protein Avidin-Biotin Capture System. This system avoids the direct interaction of a captured antibody with solid surfaces, such as plastics, which may reduce antigenicity. It has also been used to enhance the detection of DNA on nitrocellulose. Has also been used as a cell surface labelling reagent<br>References Hofmann, K., et al.: Biochemistry, 21, 978 (1982); Leary, J.J., et al.: P. Natl. Acad. Sci.

<p>Applications One of the thyroid hormones involved in the maintenance of metabolic homeostasis. Synthesized and stored as amino acid residues of thyroglobulin, the major protein component of the thyroid follicular colloid. Synthesis and secretion are regulated by the pituitary hormone (TSH).
