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

Cholecalciferol - 100IU/mg - contains 2.5g/kg active is a chemical compound known as vitamin D3. It is derived primarily from cholesterol through photochemical synthesis in animal skin exposed to ultraviolet light. The product functions as a hormone regulator by modulating calcium and phosphorus metabolism within biological systems. This process is crucial for maintaining bone density and immune system efficacy.

Delta-Tocotrienol is a natural compound, part of the vitamin E family, which is primarily sourced from the seeds and fruits of certain plants, such as annatto. This compound is a potent antioxidant, exerting its effects through the scavenging of free radicals and protection of polyunsaturated fatty acids in cell membranes from oxidative damage. Additionally, delta-Tocotrienol inhibits the enzyme HMG-CoA reductase, leading to a reduction in cholesterol synthesis.
