Revvity, 61DNPXLB, HTRF Anti-DNP mAb XL665-Conjugate, 20,000 Assay Points

MAb Anti DNP-XL665 is an IgG1 raised against DNP-BSA labeled with XL665. It exhibits high affinity for DNP-aminocaproate as well as for other DNP derivatives. This reagent can be used in both biochemical and cellular formats to study a wide variety of interactions: protein/protein, protein/peptide, protein/DNA, protein/RNA, protein/carbohydrate, protein/small molecule, receptor/ligand. HTRF can detect a broad range of affinity constants ranging from picomolar to low millimolar. 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
Assay principle In an HTRF interaction assay, one partner is labeled (directly or indirectly) with the donor, and the other with the acceptor (again, directly or indirectly). The intensity of the signal is proportional to the binding of the 2 partners. In the example shown here: MAb Anti DNP-XL665 binds to the DNP tagged partner A while partner B* binds to a specific Ab labeled with an HTRF donor. *partner B can also be biotinylated, tagged, Fc fused. In these cases, use the corresponding HTRF reagent (anti-Tag, anti-species, protA, Streptavidin) labeled with donor for the detection. Assay protocol The example on the right describes the protocol using a 20 µL final assay volume for detecting an interaction between a DNP-tagged partner A and a non-tagged partner B*. Dispense the 2 partners (10 µL), incubate, add MAb Anti DNP-XL665 (5 µL) and anti-partner B labeled with donor (5 µL), incubate and read. *partner B can also be biotinylated, tagged, Fc fused or directly labeled. In these cases, use the corresponding HTRF reagent (anti-Tag, anti species, protA, Streptavidin) labeled with donor for the detection.
