Single domain antibody
Single domain antibody (sdAb), also called nanobodies, is the variable region isolated from the antigen-binding variable domain (VHH) of camel heavy-chain only antibody or the variable domain (vNAR) of cartilaginous fish immunoglobulin new antigen receptor (IgNAR). With a size of just 15 kDa (2~4 nm), sdAb is the smallest antigen-binding fragment today discovered.
Given its small dimension, sdAb offers a series of advantages that cannot be overlooked:
- Improved tissue penetration
- Ability to trespass the blood-brain barrier
- Unique recognition of a hidden epitope
- Optimal affinity and specificity
- Highly stable over a wide range of pHs and temperatures
- Highly soluble
- Rapid clearance
- Easily re-formatted for different downstream applications
- Possibility of large-scale production
SdAb discovery services:
- Immunized camelids sdAb phage library
- Naïve camelids sdAb phage library
- Immunized shark sdAb phage library
SdAb-based research reagents:
- Primary antibody
- Secondary antibody
- Conjugated/unconjugated antibody
