Nanobody-Fc fusion - An alternative Nanobody format that combines its special epitope binding properties with the detection options for Fc-domains
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.
New iST Nano-Trap kits for immunoprecipitation (IP) and sample preparation for mass spectrometry (MS) in just 4 easy steps:
ChromoTek offers two bispecific T cell engagers:
Immunostaining in HeLa cells low expressing Tubulin-GFP.
Left: GFP signal of Tubulin-GFP (green) and DAPI stain (blue);
Right: Tubulin-GFP detection by GFP-Booster coupled to Alexa Fluor 647
We currently offer our GFP- and RFP-Booster conjugated to two different far-red dyes:
Alexa Fluor® 647 and ATTO647N.
Nanobodies are the binding domains of heavy chain only antibodies from Camelids. Nanobodies can be recombinantly produced in bacterial and other animal-free expression systems depending on the actual Nanobody construct. In contrast, classical IgG antibodies are composed of two heavy chains and two light chains and are traditionally produced using hybridoma technlogies or are isolated from a host’s blood.
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/).

Nano-Secondaries are monoclonal Nanobodies that bind to primary antibodies in a species and subtype specific manner, i.e. Nano-Secondaries are very precise secondary antibodies. They are recombinantly produced in bacterial or other animal-free expression systems; in contrast, classical mono- or polyclonal secondary antibodies are traditionally produced using hybridoma technologies or are isolated from a host’s blood.
