GFP Selector for immunoprecipitation of GFP-tagged proteins

GFP Selector Resin
GFP Selector Resin


GFP Selector features high affinity and superior capacity for immunoprecipitation experiments of GFP fusion proteins while showing negligible non-specific background. GFP Selector immobilizes a wide range of GFP derivatives. For details see our Product Specificity Chart below.

GFP Selector Resin Application

GFP Selector is compatible with physiological buffers and with high stringency buffers (see Product Data Sheet). GFP Selector provides great freedom to adjust the binding and washing conditions to the experimental needs.

GFP Selector 2 ml 2-9131-020 USD 335.00  

GFP 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. GFP Selector ...
