What is a VHH single domain antibody?
Conventionally we use IgG antibodies from mice, rat, rabbit etc. They have a size of 150kDa and are composed of 2 heavy and 2 light chains.
A group of researcher found that all members of the Camelidae family possess a special subclass IgG devoid of light chains; these antibodies consist of two heavy chains attached to variable domains (VHH).
Due to this, camelidae antibodies are much smaller, about 95kDa. The VHH alone, which is 15kDa, is also known as single domain antibody.
It is considered as the smallest naturally derived antigen-binding fragment, which is important for the development of several antibody drugs or diagnostic tools.
Advantages using VHH single domain antibody
The main advantage of VHH single domain antibodies is that they have outstanding binding properties and can be expressed at at consistently high quality without batch-to-batch variation.
Due to their high affinity and binding specificities, these types of antibodies are robust tools for a lot of bioassays and applications.

Featured VHH single domain antibody applications
There are a lot of applications, described in scientific publications, that use VHH single domain antibodies. This is due to their smaller size which leads to better tissue penetration. You can find detailed information for:
- therapeutic applications,
- crystallography applications,
- biotechnological applications,
- diagnostics applications etc.
We believe that VHH single domain antibodies are a good choice for a lot of applications and assays.
