DNA complexes migrate more slowly than free DNA lightshift chemiluminescent emsa kit when subjected to non-denaturing polyacrylamide or agarose gel electrophoresis. The whole protocol can be completed in one day, depending on the amount of time required for incubating the binding reaction. Clin Cancer Res 10 Chemiluminescent Nucleic Acid Detection Moduleavailable separately.

LightShift Chemiluminescent EMSA Kit From Pierce | Biocompare Product Review

Want to Write Reviews for Biocompare? EBNA-1 extract is provided as a control in the kit. The Kit includes lightshift chemiluminescent emsa kit for setting up and customizing protein: 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.

Also, it is suggested by the company to individually label the single stranded DNA first before annealing the two kitt together.

LightShift Chemiluminescent EMSA Kit from Thermo Fisher Scientific

Equivalent exposures using lightshift chemiluminescent emsa kit two chemiluminescent kits showed that the sensitivity of the LightShift EMSA Kit was approximately eight-fold greater than that of the digoxigenin kit. Since the kit is non-radioactive and uses the mini polyacrylamide gels, the assay is extremely fast and user friendly.


The interaction of proteins with Lightshiff is central to the control of many cellular processes including DNA replication, recombination and repair, transcription, and viral assembly. Exposure time was 30 seconds with X-ray film.

LightShift Chemiluminescent EMSA Kit from Thermo Fisher Scientific |

DNA binding reactions, a control set of DNA and protein extract to test the kit system, stabilized streptavidin-HRP conjugate to probe for the biotinlabeled DNA target, and an exceptionally sensitive chemiluminescent substrate module for detection. I recommend using smaller volumes of detection reagent than lightshift chemiluminescent emsa kit protocol suggests because I believe lightshift chemiluminescent emsa kit protocol calls for chemiluminescejt excessive volume — just make sure to cover the membrane.

Biotin end-labeled duplex DNA is incubated with a nuclear extract or purified factor and electrophoresed on a native gel. The LightShift Chemiluminescent EMSA kit has been utilized in my laboratory for approximately 6 months, and while we are still working out emsaa binding assay parameters, the kit has provided extremely clean blots during the optimization process.

Thermo Fisher Scientific Inc Lighthift 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: Briefly, while the native polyacrylamide gel in 0. Three different binding reactions are suggested for each sample: LightShift Substrate Equilibration Buffer.

The lightshigt also contains the Chemiluminescent Nucleic Acid Detection Module which contains the buffers, substrate, and streptavidin-HRP conjugate needed to detect the biotin-labeled DNA on the nylon membrane.

Because the rate of DNA migration is shifted or retarded upon protein binding, the assay is also referred to as a gel shift or gel retardation assay. Stay informed by signing up for our eNewsletters and start receiving. Mol Micro 56 2— Oltra, E. Chemiluuminescent recommend this kit for anyone interested in visually detecting protein and DNA binding while determining the specificity of the binding interaction.


Pierce offers lightshift chemiluminescent emsa kit and reagents for the detection and isolation chemoluminescent proteins, protein purification, protein labeling, interaction of proteins, and related studies. Biotinlabeled target duplexes ranged in size from bp. This kit is lightshift chemiluminescent emsa kit more chemilu,inescent than radioactive and digoxigenin methods.

Endocrinology 7 The EMSA technique is based on the observation that protein: I then expose the membrane to X-ray film.

This EMSA kit produces such clean results, it is definitely worth the money. Pierce Biotechnology is a leader in offering products for the study of proteins and related research. J Biol Chem 1— Once complete, the DNA is crosslinked to the membrane for 15 minutes using a transilluminator with a nm bulb. Lightshift chemiluminescent emsa kit protocol is fast and extremely easy to follow. Lightshift chemiluminescent emsa kit 99 26— They have provided consistent and reliable products to my laboratory throughout the years.

Biotin end-labeled duplex DNA is incubated with a protein extract and electrophoresed on a native gel. The Kti reactions were supplemented with 2.
