Restriction enzymes are a class of proteins that recognize specific DNA sequences and catalyze the cleavage of phosphodiester bonds within the DNA strand. They are used in a wide variety of applications in molecular biology and biotechnology, including DNA analysis, gene cloning and production of recombinant proteins. Restriction enzyme catalytic activity testing services are laboratory services that assess the ability of restriction enzymes to cleave DNA substrates under a variety of conditions.
Sepecific Services We Offer
Creative Enzymes offers a range of restriction enzyme catalytic activity testing services to meet the needs of our clients. Our services include:
Enzyme characterization: This service involves evaluating the properties of restriction enzymes such as their optimal temperature and pH, substrate specificity and stability under different conditions.
Activity assays: This service involves measuring the catalytic activity of restriction enzymes by monitoring the cleavage of DNA substrates using fluorometric or spectrophotometric methods.
Inhibition studies: This service involves assessing the effectiveness of inhibitors or activators on the activity of restriction enzymes.
Methods
Gel electrophoresis: This is a commonly used method to determine the activity of restriction enzymes by looking at the DNA fragments produced by the enzyme on an agarose or polyacrylamide gel. In this method, the DNA substrate is incubated with the enzyme and the resulting fragments are separated by electrophoresis.
Fluorometric assay: This method involves the use of a fluorescently labeled DNA substrate to measure the activity of the restriction enzyme. The substrate is incubated with the enzyme and the fluorescence of the lysis product is measured using a fluorometer. The rate of change of fluorescence with time is used to calculate the enzyme activity.
Spectrophotometry: This method measures the cleavage of a DNA substrate by monitoring the absorbance of light at a specific wavelength. As the enzyme cleaves the substrate, the absorbance changes so that the activity of the enzyme can be determined.
Restriction fragment length polymorphism (RFLP) analysis: This method involves digesting genomic DNA with restriction enzymes and analyzing the resulting fragments by gel electrophoresis. If there are differences in DNA sequences between individuals, this will result in different fragment sizes and thus genetic variation can be identified.
