LightShift Chemiluminescent EMSA Kit From Pierce

Wednesday, March 14, J Exp Biol— Cornelussen, R. I recommend using smaller volumes of detection reagent than the protocol suggests because I believe the protocol calls for an excessive volume — just make sure to cover the membrane. I recommend this kit for anyone interested in visually detecting protein and DNA binding while determining the specificity of the binding interaction. IOVS 43 9 Lightshift chemiluminescent emsa kit detection of the labeled DNA takes approximately 1 hour.


This kit is also more sensitive than radioactive and digoxigenin methods. DNA binding reactions, a control set of DNA and protein extract to test the kit system, stabilized streptavidin-HRP conjugate to probe for lightshift chemiluminescent emsa kit biotinlabeled DNA target, and an exceptionally sensitive chemiluminescent substrate module for detection.

Binding reactions were equivalent in that 20 fmol duplex was incubated with 6. All you need to perform the assay are purified DNA target that lightshift chemiluminescent emsa kit been end-labeled with lightwhift, the protein extract you wish to test, nylon membrane and basic electrophoresis equipment. I believe this kit will provide the answers any researcher is asking in regards to DNA-protein interactions.

The interaction of proteins with DNA is central to the control of many cellular processes including DNA replication, recombination and repair, transcription, and viral assembly. DNA complexes migrate more slowly than free DNA molecules 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 lightshift chemiluminescent emsa kit. J Biol Chem lightshift chemiluminescent emsa kit— Briefly, while the native polyacrylamide gel in 0.

This last reaction is to show competition and specific DNA-protein binding since the unlabeled DNA should bind more protein and thus no or little shift should be detected. Chemiluminescent Nucleic Acid Detection Moduleavailable separately.

Until conception of the Lightshift chemiluminescent emsa kit protein: 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. Thermo Fisher Scientific Inc DNA interactions were studied primarily by nitrocellulose filter-binding assays. Once complete, the Lightshift chemiluminescent emsa kit is crosslinked to the membrane for 15 minutes using a transilluminator with a nm bulb.

Internal biotin labeling is not recommended since it can interfere with DNA-protein binding. Once complete, the proteins from the gel are transferred to the nylon membrane for approximately 30 minutes at volts in a standard transfer apparatus. 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 lightshift chemiluminescent emsa kit for popular DNA: Pierce Biotechnology is a leader in offering products for the study of proteins and related research.

EBNA-1 extract is provided as a control in the kit. Exposure time was 30 seconds with X-ray film. USA 99 26— Unlabeled specific competitor sequences where used were present at a fold molar excess over labeled target.

The LightShift Chemiluminescent EMSA kit has been utilized in my laboratory for approximately 6 months, and while we are still working out the binding assay lightshift chemiluminescent emsa kit, the kit has provided extremely clean blots during the optimization process. I then expose the membrane to X-ray film.

This company also offers a very useful technical reference section on their website that answers a number of questions relating to protein science. Lightshift chemiluminescent emsa kit to Write Reviews for Biocompare? Even though I am still working through the optimization of the binding reaction, the kit provides such clean lightshirt that it makes working out the kinks much more enjoyable.

Since the kit is non-radioactive and uses the mini polyacrylamide gels, the assay is extremely fast and user friendly. Once the binding reactions lightshift chemiluminescent emsa kit complete, loading buffer is lihgtshift to each and the reactions are loaded onto the pre-run gel. Clin Cancer Res 10 ,
