Overview
MAb Anti cmyc-d2 is an IgG1 raised against a synthetic peptide corresponding to the 408-439 sequence of human c-myc protein labeled with d2. It recognizes the EQKLISEEDL motif and is specific for human c-myc, although a slight cross-reaction has been observed with murine c-myc at high antibody concentration.
This reagent can be used in both biochemical and cellular formats to study a wide variety of interactions: protein/protein, protein/peptide, protein/DNA, receptor/ligand..
HTRF can detect a broad range of affinity constants ranging from picomolar to low millimolar.
Benefits
- LARGE COMPLEXES DETECTION
- BATCH-TO-BATCH REPRODUCIBILITY
- LOW TO HIGH KD DETECTION
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 cmyc-d2 binds to the c-Myc 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 c-Myc-tagged partner A and a non-tagged partner B*.
Dispense the 2 partners (10 µL), incubate, add MAb Anti cmyc-d2 (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.
Build HTRF interaction assays for your specific application
Reagents are sold by the number of tests (20 µL reactions). Antibodies conjugated to XL665 or d2 are supplied on the basis of 20 ng of antibody per well. The amount of active moiety per vial is also provided (as well as the number of tracers per vial - see product description sheet). The active moiety is defined as the active part of a conjugate (e.g. antibody).
How do the number of tests relate to active moiety?
The average conjugate quantity per well reflects overall biological material content. Using the active moiety amount is generally preferred to the quantity of total conjugate. For Cryptate and d2 conjugates, the total conjugate amount equals that of the active moiety, since the molecular weight of the label is negligible. This is not the case for XL665 labeled entities for which the quantity of total conjugate will vary depending on the final molar ratio of the XL665 conjugate, however, the amount of active moiety, provided by Cisbio, is constant and based on the number of tests ordered.
Recommended quantities of Cryptate and XL665 conjugates
Cryptate conjugates must not be excessive in order to prevent reader saturation and an unacceptable level of background. In most cases, a cryptate concentration of 1 to 5nM is appropriate, and will generate 20,000 to 80,000 cps at 620 nm depending on the HTRF compatible reader used. The XL665 conjugate must match its assay counterpart as closely as possible in order for the maximum number of biomolecules to be tagged with the XL665 acceptor. Thus, to detect a tagged molecule at an assay concentration of 20nM, the concentration of anti-Tag-XL665 should be equimolar or higher.
