What are heavy chain antibodies?

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.

Introduction

Fluorescent proteins (FPs) have been used as protein tags since the mid-1990s mainly for cell biology and fluorescence microscopy. These tags have not only revolutionized cell biology by enabling the imaging of almost any protein, they are also used in biochemical applications. An important example is the immunoprecipitation and affinity purification of FP-tagged proteins, which was enabled by the development of affinity resins with high yield, purity, and affinity such as ChromoTek’s Nano-Traps (https://www.chromotek.com/products/detail/product-detail/nano-traps/).

In this blog we provide a review of

• green fluorescent proteins
• red fluorescent proteins
• self-labelling proteins, that require the covalent coupling of a fluorescent molecule

The ChromoTek rat monoclonal anti-RFP antibody 5F8 has been cited for the use in immunofluorescence (IF) and immunohistochemistry (IHC) experiments by 91 peer reviewed articles. It is thus the anti-RFP antibody referenced most often at the database citeAB. This top rank is the result of its performance and quality. The anti-RFP antibody 5F8 recognizes common RFP variants including mCherry, mPlum, mRFP, mRFPruby.
