Spermidine trihydrochloride by MP Biomedicals is a high grade reagent. This is a derivative of spermidine, which is a polyamine compound found in ribosomes and living tissues. This reagent is available as a white powder which is soluble in water. These compounds serve vital roles in cell survival. Spermidine is known to regulate plant growth, assisting the in-vitro process of transcribing RNA, and it inhibits NOS. Sources of spermidine include aged cheese, mushrooms, soy products, legumes, corn, and whole grains CAS No. 334-50-9 Quantity Provided: 5 gm per pack Molecular Formula: C7H19N3.3HCl Molecular Weight 254.6 Soluble in waterSpermidine trihydrochloride is widely used in chemical and biological sectors. Spermidine binds to and precipitates DNA, and may be used for purification of DNA binding proteins. It stimulates T4 polynucleotide kinase activity. Its role in cell growth processes finds many applications in research. It can be used in electroporation while transferring the DNA into the cell under the electrical impulse. It is also plant growth regulator, promoting somatic embryogenesis. Spermidine trihydrochloride has been used in fourier transform infrared spectroscopy (FTIR) characterization and in zeta-potential measurements.
