Tips and tricks for immunoprecipitation of low abundant proteins
Protein abundance is crucial for immunoprecipitation
During an immunoprecipitation (IP), the protein of interest (POI) is pulled down with a specific antibody or Nanobody conjugated to beads such as agarose or magnetic agarose. Unbound sample content, for example, other proteins, cell debris, and lipids, is removed by washing, while the precipitated protein is enriched on the beads.
Topics: GFP-Trap, GFP Immunoprecipitation
Overview of the most recent Spot Peptide-Tag & Spot-Nanobody publications
More and more publications are coming up using ChromoTek’s Spot-Tag system, the first peptide-tag specific Nanobody system for universal capture & detection applications.

Seizing the day: How to save time on your immunoassay experiments
When time in the lab is limited, learn how to save precious hours on your immunoprecipitation, immunofluorescence and western blotting experiments.
Due to the current situation with the COVID-19 pandemic, many researchers around the world are faced with restrictions on time and resources in the lab. As we adapt to these changes, the pressure is on to find ways to save time without compromising on results. Proteintech and ChromoTek offer solutions to save you hours on your current immunoassay protocols, helping you achieve publication worthy results in a fast and reliable manner.
Topics: Immunoprecipitation, Immunofluorescence, GFP, Nano-Secondaries
The conjugation of the binding domains of camelid heavy chain antibodies, also known as VHHs or Nanobodies, to fluorescent dyes is generating versatile tools for fluorescence microscopy applications like immunofluorescence (IF) and super resolution microscopy (SRM): The small size Nanobodies provide better penetration into tissue and dense cell compartments, plus the small label to epitope displacement provides higher resolution. In addition, the Nanobodies’ high affinity binding to epitope makes them attractive probes for other assays like ELISA.
ChromoTek, part of Proteintech group, provides multiple fluorescent dye (Alexa Fluor® and ATTO) conjugated Nanobodies that are optimized by application:
Neuropilin-1 joins ACE2 as SARS-CoV-2 gateaway
Using both Proteintech and Chromotek antibodies, Davy and colleagues published a landmark paper in Science late in 2020, detailing how Neuropilin-1 is required for SARS-CoV-2 host cell entry.
V5 Tag: Properties, origin, specifications, antibodies & Nanobodies
V5 tag is a short peptide tag for detection and purification of proteins. The V5 tag can be fused/cloned to a recombinant protein and detected in ELISA, flow cytometry, immunoprecipitation, immunofluorescence, and Western blotting with antibodies and Nanobodies.
Topics: Immunoprecipitation, V5
Parts of them are used as epitope tags
Epitope tags, i.e. short peptide tags are commonly used, versatile, and convenient tools for multiple capture and detection applications including immunofluorescence, immunoprecipitation, affinity purification, and Western blotting.
