- Characteristics
-
GFP-Catcher 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-Catcher thus features high affinity and superior capacity for GFP fusion proteins while showing negligible non-specific background.
GFP-Catcher immobilizes a wide range of GFP derivatives.
GFP-Catcher is compatible not only with physiological buffers but also with high stringency buffers.
GFP-Catcher thus provides great freedom to adjust the binding and washing conditions to the experimental needs. - Components

- Product Specific Information
-
Our GFP Catcher is a product based on the GFP pull-down technique used to isolate GFP fusion proteins from cell lysates. It consists of special magnetic beads (product ABIN7272855) or agarose beads (product ABIN5311508) coated with an antibody against GFP. These beads allow efficient and selective binding to GFP or GFP-fused target proteins.
The application of GFP Catcher is similar to the GFP pull-down method. First, the protein of interest is expressed in the cells with it fused to GFP. Then, the cell lysate is prepared to extract the target proteins. The GFP catcher beads are then added to the cell lysate and bound to these proteins by specifically binding to the GFP or GFP fusion protein.
After the beads with the bound target proteins are isolated, thorough purification is performed to remove components that are not specifically bound. Finally, the target proteins can be separated from the beads and used for further analysis such as immunoblotting or mass spectrometry.
GFP Catcher offers the advantage of quick and easy isolation of GFP fusion proteins. It is a useful tool for protein analysis and allows efficient identification of proteins interacting with GFP fusion protein. GFP Catcher is widely used in cell biology research to study protein-protein interactions and deepen the understanding of cellular processes.
