Beyond BrdU, New Generation Cell Proliferation Imaging Analysis Kit (EdU Method)

Common methods of cell proliferation
mainly include MTT method, WST-1 method and CCK-8 method, which are mainly
based on the activity of cells, thus reflecting the overall proliferation
effect, but unable to detect individual proliferating cells. Recognized as the
most accurate method to detect cell proliferation is to directly detect DNA
synthesis in cells. Previously, BrdU method was the most commonly used method.
However, the method requires DNA denaturation (such as acid denaturation,
thermal denaturation or DNase digestion) to expose BrdU, thus binding to BrdU
antibody. The whole experiment has many influencing factors and poor stability.

Abbkine innovates and develops EdU
method based on EdU incorporation and subsequent click reaction to solve this
application difficulty:

Product name	Cat#	Fluorescent characteristic
Cell Proliferation EdU Image Kit (Green Fluorescence)	KTA2030	AbFluor 488 Ex/Em = 501/525 nm
Cell Proliferation EdU Image Kit (Orange Fluorescence)	KTA2031	AbFluor 545 Ex/Em = 546/565 nm

Principle：EdU (5-ethynyl-2´-deoxyuridine) is a nucleoside analog of thymidine and is incorporated into DNA during active DNA synthesis. Comparing to BrdU assays, the EdU-Click Assays are not antibody based and therefore do not require DNA denaturation (typically using HCl or heat or digestion with DNase) for detection of the incorporated nucleoside. Detection is based on a click reaction, a copper-catalyzed covalent reaction between an azide and an alkyne, is complete within 30 minutes.

Kit components	Advantage
