Nanotraps® are a new format of binding proteins by ChromoTek that are extremely small, highly stable and utmost reliable. They are therefore ideal tools for a multitude of analytical and preparative applications, e.g. purification of fusion proteins for proteomics, immune fluorescence detection or ELISA studies, using for instance green fluorescent protein (GFP).

Nanotraps® are superior to conventional antibodies in many respects: no lot-to-lot variations, easier handling, and up to 70% shorter assay times. GFP-Trap® and RFP-Trap® are efficient reagents for functional and biochemical studies of fluorescent proteins.

The GFP-Trap® and RFP-Trap® featuring:

• robust and versatile tool for biochemical analyses
• short incubation times (5 - 30 min)
• quantitative isolation of fusion proteins and transiently bound factors from cell extracts or organelles (from all organisms)
• low unspecific binding
• no contaminating heavy and light chains of conventional antibodies
• works perfectly for Chromatin Immunoprecipitation (ChIP)
