The M65® ELISA was introduced in 2004 and intended for the determination of total cell death of epithelial cells. A combined use of M65® ELISA and M30 Apoptosense® ELISA facilitates the determination of cell death mode (apoptosis or necrosis).
The M65 EpiDeath® ELISA is based on the same monoclonal antibodies as the M65® ELISA, except mAb M5 is used as the capture antibody (mAb M6 is used as capture antibody in the M65® ELISA). Reaction buffers have also been slightly modified This CK18 kit is manufactured differently and thus measures the (complex bound) CK18 epitopes differently than the M65® ELISA, which leads to a better discrimination between low or normal and high levels. It has a broad range as well.
The M65 EpiDeath ELISA is recommended whenever a customer wants to identify cell death with high sensitivity and specificity. The M65 ELISA is the better choice for customers intending to determine the cell death mode when using in combination with the M30 Apoptosense ELISA, especially when using a mathematical approach to describe the distribution between apoptosis and necrosis.
