Details

Internucleosomal DNA fragmentation is a hallmark of apoptosis in mammalian cells. BioVision’s Apo-BrdU-Red In Situ DNA Fragmentation Assay Kit provides complete components including positive and negative control cells for conveniently detecting DNA fragmentation by fluorescence microscopy or flow cytometry. The kit utilizes Br-dUTP (bromolated deoxyuridine triphosphate nucleotides) which is more readily incorporated into DNA strand breaks than other larger ligands (e.g., fluorescein, biotin or digoxigenin). The greater incorporation gives rise to brighter signal when the Br-dUTP sites are identified by a Red fluorescence labeled anti-BrdU monoclonal antibody. The assay is suitable for studying apoptosis with GFP transfected cells.

What is the spectrum of excitation and emission of the BrdU-Red?
The BrdU-Red monoclonal antibody emits fluorescence at 576nm when excited at 488nm. The wavelengths can shift +/-10 to 20nm based on the instrument.
Can this assay differentiate between necrosis/apoptosis?
TUNEL assay is positive for both necrotic and apoptotic cells and hence cannot distinguish. You can run DNA gel to differentiate between them- while necrotic cells will show a smear due to non-specific cleavage, apoptotic cells has activated endonucleases that cleaves the DNA into fragments of approximately 180-200bp that looks like a ladder on the DNA gel.
What is the exact volume of sample required for this assay?
There is no specific volume we can recommend for the amount any sample to be used since it is completely sample concentration and quality based. You have to do a pilot expt with multiple sample volumes to determine the optimal volume which gives a reading within the linear range of the standard curve. Please refer to the citations for this product to see what other clients have used with similar sample types.
Do you have trial sizes of this kit?
Unfortunately, we do not have trial sizes of this kit available. However, if you are based in the US or Canada, we will give you a 10% off list price introductory discount on its purchase price. If you are based out of this area please contact your regional BioVision distributor.
What is the shelf life of this kit?
 BioVisions’s assay kits expire 6 months from the date of shipment. Some components of the kit may expire sooner as mentioned in the data sheet
Can we purchase individual components of this kit?
Yes, you can purchase any of the kit's components without the whole kit. Please refer to the component Cat #s mentioned on the datasheet for ordering.
Can we use an alternate buffer for sample preparation (cell lysis, sample dilutions etc)?
Our assay buffers are optimized for the reactions they are designed for. They not only contain some detergents for efficient lysis of your cells/tissue, but also contain some proprietary components required for the further reactions. Therefore, we highly recommend using the buffers provided in the kit for the best results.
