Anti-GFP Nanobeads

   The green fluorescent protein (GFP) is a protein exhibiting bright green fluorescence when exposed to ultraviolet light and frequently used as reporters and fusion tag. AlpaLife's anti-GFP Agarose Beads are perfect tools for separating GFP-fusion proteins and their binding partners from cell extract. By coupling high-affinity anti-GFP VHH antibodies (also known as single domain of camelid antibodies, or nanobodies *) to agarose beads, GFP Beads exhibit high specificity and strong affinity to GFP and GFP-fusion proteins.

1. Question: Can I use GFP Agarose Beads to immunoprecipitate EGFP- or RFP-fusion proteins and their partners?
Answer: Yes, GFP Agarose Beads have been experimentally tested on GFP, EGFP and RFP tagged proteins.

2. Question: Can I use a different Lysis Buffer with higher NaCl and NP40 concentration?
Answer: Yes, the nanobody we conjugated with agarose beads is stable even in harsh buffer conditions.

3. Question: Can I incubate GFP Agarose Beads with cell lysate overnight at 4 °C to increase their binding?
Answer: Yes, but the binding efficiency between GFP Agarose Beads and GFP after 1 h, 2 h, 3 h, and overnight incubations are almost the same. Therefore, in most situations, 1 h incubation should be enough and can give good results.
