Description générale

A ready-to-use solution of high quality single-stranded template DNA isolated from the testes of salmon. The solution is supplied at a concentration of 9 - 12 mg/ml .

Application

Deoxyribonucleic acid, single stranded from salmon testes is suitable for use as a blocking agent in Southern hybridizations. It was used for in situ hybridization histochemistry of bone marrow biopsy samples and human blood monocyte subpopulations.
Many factors contribute to the signal-to-noise ratio in nucleic acid hybridizations. These factors include the presence of solvent (formamide), hybridization temperature, length of hybridization, volume of hybridization solution, degree and method of agitation, use of blocking reagents, concentration and specific activity of the probe, use of molecular agents to increase the rate of nucleic acid reassociation, and the degree of stringency used during the washing of the membrane.

In order to decrease any non-specific hybridization of the probe to a substrate, blocking agents must be used. Generally, a combination of blocking reagent, detergent, and denatured, fragmented DNA is used to accomplish this. Sigma offers sonicated, denatured DNA from a variety of species for use as a blocking agent in Northern and Southern blotting and other nucleic acid hybridization techniques.

Notes préparatoires

This DNA is ethanol precipitated and sonicated to produce single-stranded fragments which comigrate with the 587 and 831 base pair marker fragments.

Autres remarques

DNA in solution will reanneal on standing at room temperature so it is recommended to boil the solution for 10 minutes and then cool on ice for at least 5 minutes prior to use.

Introduction to Yeast Transformation

Transformation is the process by which exogenous DNA is introduced into a cell, resulting in a heritable change or genetic modification. This was first reported in Streptococcus pneumoniae by Griffith in 1928. Transforming principle of DNA was demonstrated by Avery et al. in 1944.
