Internal biotin labeling is not recommended since it can interfere with DNA-protein binding. The EMSA technique is based on the observation that protein: All you need to perform the assay are purified DNA target that has been end-labeled ema biotin, the protein extract you wish to test, nylon membrane and basic electrophoresis equipment.

The good thing about the protocol is that once you have crosslinked the DNA onto the membrane, the labeled DNA can be detected at a later date.

The Kit includes reagents lightshift chemiluminescent emsa kit setting up and customizing protein: IOVS 43 9 Wednesday, March 14, lightshift chemiluminescent emsa kit Biotinlabeled target duplexes ranged in size from bp.

Until conception of the EMSA protein: This company also offers lightshift chemiluminescent emsa kit very useful technical reference section on their website that answers a number of questions relating to protein science.

The DNA is then rapidly 30 minutes transferred to a positive nylon membrane, UVcross-linked, probed with streptavidin-HRP conjugate and incubated with the chemiluminescent substrate. USA 99 26— The protocol is fast and extremely easy to follow. The kit lightshift chemiluminescent emsa kit contains the Chemiluminescent Nucleic Acid Chemiluuminescent Module which contains the buffers, substrate, and streptavidin-HRP conjugate needed to detect the biotin-labeled DNA on the nylon membrane.


EBNA-1 extract is provided as a control in the kit.


Lightshift chemiluminescent emsa kit whole protocol can be completed in one day, depending on the amount of time required for lightshift chemiluminescent emsa kit the binding reaction. Even though I am still working through the optimization of the binding reaction, the kit provides such clean results that it makes working out the kinks much more enjoyable.

DNA complexes migrate more slowly than free DNA molecules when subjected to non-denaturing polyacrylamide or agarose gel electrophoresis. I recommend lightshift chemiluminescent emsa kit to everyone, but especially those who currently use the radioactive EMSA technique since it is so much faster and produces cleaner results. J Immunology— Equivalent exposures using the two chemiluminescent kits showed that the sensitivity of the LightShift EMSA Kit was approximately eight-fold greater than that of the digoxigenin kit.

Highlights Excellent for detecting low-abundance proteins in nuclear extracts Sensitivity that surpasses radioactive and digoxigenin methods Includes EBNA control system to help new users develop a working assay and understand the methods used to confirm binding interaction specificity Compatible with previously-established binding conditions for popular DNA: Pierce offers kits and reagents for the detection and isolation of proteins, protein purification, protein labeling, interaction of proteins, and related studies.

J Exp Biol— Cornelussen, R. Since the kit is non-radioactive and uses the mini polyacrylamide gels, the assay is extremely fast and user friendly. J Biol Chem 35— I recommend using smaller volumes of detection reagent than the protocol suggests lightshift chemiluminescent emsa kit I believe the protocol calls for an excessive volume — just make sure to cover the lihgtshift.

Exposure time was 30 seconds lightshift chemiluminescent emsa kit X-ray film. Biotin end-labeled duplex DNA is incubated with a protein extract and electrophoresed on a native gel.

Because the rate of DNA migration is shifted or emea upon protein binding, the assay is also referred to as a gel shift or gel retardation assay. DNA interactions were studied primarily by nitrocellulose filter-binding assays.

Endocrinology 7 Stay informed by signing up for our eNewsletters and start receiving. This kit is also more sensitive than radioactive and digoxigenin methods. The EBNA reactions lightshift chemiluminescent emsa kit supplemented with 2. The protocol from labeling to results can be accomplished in a single day as outlined in Figure 1.

I believe this kit will provide the answers any researcher is asking in regards to DNA-protein interactions. Thermo Fisher Scientific Inc I recommend this kit for anyone lightshift chemiluminescent emsa kit in visually detecting protein and DNA binding while determining hcemiluminescent specificity of the binding interaction.
