SNAP-tag and CLIP-tag are self-labeling protein tags. The SNAP-tag protein and the CLIP-tag protein can be fused to a protein of interest (POI) and used for cellular and biochemical analysis.

HaloTag is a protein tag. The HaloTag protein can be fused to your protein of interest (POI) which enables it for cellular and biochemical analysis. It can also be used for live cell imaging.

Bispecific T cell engagers are bispecific antibodies designed to link T cells with cancer cells. The simultaneous binding of the bispecific antibody to T cell and tumor cell initiates the activation of the T cell. For this purpose, the bispecific antibody carries two antigen binding domains against the T cell (often CD3 T cell receptor) and against a cell surface protein of the tumor cell.

ChromoTek offers two bispecific T cell engagers:

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
