Overview

Description

mCherry-Alpaca-Biotin™ Anti-mCherry tag Alpaca Nanobody(VHH) Conjugated Biotin 

Reactivity

Detect transfected mCherry tag fusion proteins expressed in E. coli, yeast, insect cell, mammalian cell, or in vitro transcription/translation systems. All systems that express mCherry tag fusion protein are suitable.

Tested applications

It can be coupled with streptavidin, or streptavidin-HRP,  or streptavidin-fluoresent dye, or streptavidin-beads.

Applications

Highlights

Benefits Of Alpaca nanobody

 

No Fc fragment of ordinary antibodies, so there is no non-specific binding of Fc to the cell surface Fc receptor of immune cells in flow cytometry experiments

Highly specific binding

Low background

High affinity

High stability

Alpaca nanobody is a small molecule with molecular weight of only 13kD (Conventional rabbit or mouse antibody is 150kD), so it can easily enter permeablized cells

Animal-free production, recombinant expression in yeast and affinity purified
