Revvity, 64NCLTPEG, HTRF Human Total Nucleolin Detection Kit, 500 assay points

Overview
Nucleolin is protein that is mostly localized in the nucleus, where it is involved in ribosome biogenesis by binding to and stabilizing pre-RNA. It also plays several other roles in conjunction with ribosomes, such as RNA transcription regulation via transcription factor binding and nucleus-cytosol mRNA trafficking. The phosphorylation state of nucleolin regulates its activity by increasing its binding affinity for RNA, and is especially enhanced in response to cellular stress and DNA damage. Abnormal phosphorylation of nucleolin is recognized as a potential source of lack of regulation of mRNA transcription, which can alter the expression of pro- and anti-oncogenic genes and contribute to cancer development or progression.
How it works
Total Nucleolin assay principle

The Total Nucleolin assay measures Nucleolin levels in cells. Unlike Western Blot, the assay is entirely plate-based and does not require gels, electrophoresis, or transfer. The assay uses 2 antibodies, one labeled with a donor fluorophore and the other with an acceptor. In the presence of Nucleolin, the labeled antibodies form an immune complex, bringing the donor fluorophore into close proximity to the acceptor and generating a FRET signal. The signal intensity is directly proportional to the concentration of total protein present in the sample.

 
Total Nucleolin two-plate assay protocol

The two-plate protocol involves culturing cells in a 96-well plate before lysis, then transferring lysates into a 384-well low volume detection plate before the addition of Total Nucleolin HTRF detection reagents. This protocol enables the cells' viability and confluence to be monitored.

 
Total Nucleolin one-plate assay protocol

Detection of Total Nucleolin 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 allows miniaturization while maintaining robust HTRF quality. Application-Cell Signaling
