Record number of papers citing the GFP-Trap group products in 2011

The following are references in regards to GFP Trap published in the second half of 2011 (not a complete list); a high quality GFP-binding protein based on a single domain antibody derived from Camelids. It is characterized by a small barrel shaped structure (13 KDa, 2.5nm X 4.5 nm) and a very high stability (stable up to 70°C, functional within 2M NaCl or 0.5% SDS). With much greater stability, specificity, and affnity, GFP-Trap®, the recent addition to antibodies for immunoprecipitation, should make GFP the most suitable tag for immunoprecipitation assays.

About 50 Papers Cited the Use of GFP-Trap Camelid Antibody So Far in 2011

With their ability to quantitatively pulldown GFP-tagged proteins, GFP-Trap (or RFP-Trap for DsRed-derived fluorescent proteins) beads have gained ground in becoming the reagent of choice for immuno-coprecipitation. The complexes isolated from GFP-Trap agarose or magnetic beads can be easily analyzed without interference from light or heavy IgG chains typically present after monoclonal or polyclonal antibody precipitation. Since the market launch of GFP-Trap, in each of the past 3 years, the number of publications citing GFP-Trap more has than doubled and there is no sign of that rate slowing down any time soon.

In 2011 alone, 48 research groups have published their results with data generated through use of GFP-Trap (not including other related products such as GFP-Booster, GFP-MultiTrap). Research topics in these recent publications include identification of domains of the zinc finger protein 638 (ZNF638) that interacts with C/EBPb when promoting adipocyte differentiation [1]; identification of phosphorylation site on Cdc42-associated kinase (Ack) by LC-MS/MS after immunoprecipitation [2]; and analysis of the activities of myosin heavy-chain kinases (MHCKs) in wild-type vs Htt mutant Dictyostelium discoideum, a cellular model for studying the Huntingon disease [3].

The use of GFP-Trap beads is a simple bind-wash-elute procedure that involves just one antibody already immobilized on either agarose or magnetic beads. Camelid antibodies, especially their VHH single domain fragments such as those used in GFP-Trap or RFP-Trap, are very stable (they can be shipped and temporarily stored at room temperature). The consistency of performance is very high; as a matter of fact, this line of products requires the lowest amount of technical support among all of our products. If you are still using tags like FLAG, V5, HA, etc., you should consider trying GFP as both a fluorescence and co-IP tag in your future experiments for obtaining results you previously could not obtain.
