Revvity, 64NE1PEG, HTRF Human Total MEK1 Detection Kit, 500 Assay Points

Overview
The HTRF total MEK1 assay kit is designed for the quantitative detection of total MEK1, phosphorylated and unphosphorylated, to normalize the phosphorylation status of MEK1. It is the ideal assay for studying the RAS-RAF-MEK cascade in the MAPK/ERK pathway. Phosphorylated by RAF, this dual specificity mitogen-activated protein kinase is responsible for the phosphorylation of ERK, one of the most important signaling nodes, and protein kinase in cell proliferation, survival, and differentiation pathways.
HTRF assays offer many advantages over other technologies:

Homogeneous add-and-read format
No wash steps
Low background
Straightforward miniaturization from 96- or 384-well microplates to high density assay formats such as 384-well low volume and 1536-well plates
Stable signal, providing flexibility in time of readout or size of assays
How it works
Total-MEK1 assay principle
The Total-MEK1 assay quantifies the expression level of MEK1 in a cell lysate. Contrary to Western Blot, the assay is entirely plate-based and does not require gels, electrophoresis or transfer. The Total-MEK1 assay uses two labeled antibodies: one coupled to a donor fluorophore, the other to an acceptor. Both antibodies are highly specific for a distinct epitope on the protein. In presence of MEK1 in a cell extract, the addition of these conjugates brings the donor fluorophore into close proximity with the acceptor and thereby generates a FRET signal. Its intensity is directly proportional to the concentration of the protein present in the sample, and provides a means of assessing the proteins expression under a no-wash assay format.

 

Total-MEK1 2-plate assay protocol
The 2 plate protocol involves culturing cells in a 96-well plate before lysis then transferring lysates to a 384-well low volume detection plate before adding Total MEK1 HTRF detection reagents. This protocol enables the cells' viability and confluence to be monitored.

 

 Total-MEK-1-plate assay protocol
Detection of total MEK with HTRF reagents can be performed in a single plate used for culturing, stimulation and lysis. No washing steps are required. This HTS designed protocol enables miniaturization while maintaining robust HTRF quality. Application-Cell Signaling
