Thermo Scientific™ HotStart-IT Binding Protein

HotStart-IT™ Binding Protein is the active component in a novel hot start technology called primer sequestration. In general, hot start PCR methods reduce or eliminate non-specific primer-extension products formed at lower temperatures during assembly of PCR reactions. At these less stringent annealing temperatures, primers may bind non-specifically, which often leads to unwanted amplification products and primer-dimers. In order to resolve this problem, we have produced a high-quality DNA binding protein that is especially useful at sequestering primers at lower temperatures making them unavailable for use by a polymerase (Fig. 1). This primer-sequestration technique effectively blocks DNA synthesis from mis-priming events at lower temperatures. Following the initial denaturation step during PCR, the protein is inactivated and the primers are free to participate in the amplification reaction. Unlike other hot start methods, such as antibodies or chemical modifications, the binding protein is compatible with a variety of thermostable polymerases. HotStart-IT Binding Protein has been designed for PCR applications that demand extremely high specificity and sensitivity and is thoroughly tested for purity and performance.
