About Nanobody
Nanobody (Nb), i.e. variable domain of heavy chain of heavy-chain antibody, was first reported by Belgian scientists in the journal Nature in 1993. It is a single-domain antibody composed of a variable region (VHH) of natural heavy chain antibody that lacks a light chain in camelides (camel, llama, alpaca and their close relative species). The antibody contains only one heavy chain variable region (VHH) and two conventional CH2 and CH3 regions. The VHH crystal is a cylinder with a diameter of 2.5 nm and a length of 4 nm. The molecular weight is only 15 kDa, so it is also called a nanobody (Nanobody, Nb).

Platform Advantages
Case example

Purity ≥ 95%; endotoxin <50 EU/mg of protein.

The two-step chromatography method was developed.

Affinity chromatography: after affinity with A3, purity reached 94.1%

Anion exchange chromatography: after the use of 50HQ, yield reached 73.9% and purity reached 98.1%

Meets process target after endotoxin test.
