Revvity, 62HGRZBPEH, HTRF Human Granzyme B Detection Kit, 10,000 Assay Points

Overview
Granzyme B (also called Cathepsin G-like 1, Cytotoxic T-lymphocyte proteinase 2, Fragmentin-2, Granzyme-2, or Human lymphocyte protein) is found in cytotoxic lymphocytes, NK (natural killer) cells, and cytotoxic T cells. Secreted with Perforin, which creates a pore in the cell membrane, it enters the target cell's cytoplasm and triggers apoptosis through caspase activation.
This kit is designed for the rapid detection of human Granzyme B in cell supernatant and whole cells. The assay enables high throughput without any washing steps, thereby saving time compared to ELISA.
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
Assay principle
Human Granzyme B is a sandwich immunoassay involving two specific anti-human Granzyme B antibodies, respectively labelled with Europium Cryptate (donor) and d2 (acceptor). The intensity of the signal is proportional to the concentration of Granzyme B present in the sample.

Assay Protocol
The assay protocol, using a 384-well small volume white plate or a Revvity low volume 96-well plate (20 µL final), is described on the right. 16 µL of cell supernatant, sample, or standard are dispensed directly into the plate for detection by HTRF reagents. The antibodies labelled with HTRF donor and acceptor can be pre-mixed and added in a single dispensing step to further streamline the assay procedure. The assay can be run in 96- to 384-well plates by simply resizing each addition volume proportionally. Application-Protein Quantification
