RFP Selector for immunoprecipitation of RFP-tagged proteins

RFP Selector Resin
RFP Selector Resin


RFP Selector features high affinity and superior capacity for immunoprecipitation experiments of RFP fusion proteins while showing negligible non-specific background. RFP Selector immobilizes a wide range of RFP derivatives including mCherry. For details see our product specifications below.

RFP Selector is compatible with physiological buffers and with high stringency buffers. RFP Selector provides great freedom to adjust the binding and washing conditions to the experimental needs.

RFP Selector 2 ml 2-9141-020 USD 335.00  

RFP Selector is based on a high-affinity single-domain antibody (sdAb) that is covalently immobilized on 4% cross-linked agarose beads. The innovative, oriented and selective attachment via a flexible linker guarantees a high accessibility of the sdAbs and largely eliminates batch-to-batch variations. Due to the single-chain nature of sdAbs and their covalent attachment, no "leakage" of light and heavy chains from IgGs is observed during elution with SDS sample buffer. RFP Selector ...
