Proteintech Group Inc Viability/Cytotoxicity Assay Kit for Animal Live & Dead Cells (Calcein AM, PI Method)
Viability/Cytotoxicity Assay Kit for Animal Live & Dead Cells (Calcein AM, PI method) provides dual fluorescence staining for the detection of living and dead cells. The two probes in the kit eflect cell viability by measuring intracellular esterase activity and plasma membrane integrity. This kit can be used for fluorescence microscopes, flow cytometers, microplate readers and other fluorescence detection systems. This kit can be used for most eukaryotic mammalian samples, but not to fungi and yeast.

Aat Bioquest Amplite™ Colorimetric Alanine Aminotransferase Assay Kit *Blue Color*
Alanine aminotransferase (ALT), also called serum glutamate pyruvic transaminase (GPT), is a member of transferase family.
Dojindo Molecular Technologies Inc DNA DAMAGE QUANTIFIC KIT (20 SAMPLES) is a colorimetric microplate assay and can determine the number of abasic sites in genomic DNA samples.
Oxidative damage to DNA is a result of its interaction with reactive oxygen species (ROS), in particular the hydroxy radical. Hydroxy radicals, which are produced from superoxide anion and hydrogen peroxide by the Fenton reaction, produce multiple modifications in DNA. Oxidative attacks by hydroxy radicals on the deoxyribose moiety leads to the release of free bases from DNA, generating strand breaks with various sugar modifications and simple abasic sites (AP sites). In fact, AP sites are one of the major types of damage generated by ROS. The Aldehyde Reactive Probe reacts specifically with an aldehyde group present on the open ring form of the AP sites. DNA Damage Quantification Kit contains all the necessary solutions for detecting between 1 to 40 AP sites per 1 x 105 base pairs.
