Product Description
| Product Name | Anti-Kappa opioid receptor Nanobody (VHH), Recombinant, Purified |
| Description | A purified, engineered single-domain antibody (VHH / nanobody) against Kappa opioid receptor, for research applications including detection, capture and imaging. |
| Target / Specificity | Kappa opioid receptor |
| Sequence | This nanobody is an engineered variant based on PDB 6VI4, with higher affinity and stability than the original published sequence. |
| Format | Purified recombinant single-domain antibody (VHH / nanobody), carrier-free |
| Tag & Expression | C-terminal 6×His tag; secreted from HEK293 cells and purified by one-step IMAC from the culture medium. |
| Molecular Weight | ~14 kDa (single VHH domain + His6; ~1/10 the size of a conventional IgG) |
| Purity | >90% by SDS-PAGE |
| Quantity | 100 µg |
| Formulation | PBS with 50% glycerol (carrier-free); 0.02% sodium azide |
| Applications | ELISA, Western blot (WB), immunofluorescence (IF), immunoprecipitation (IP), affinity capture |
| Structural Epitope | Epitope mapped from the experimental VHH–antigen complex (PDB 6VI4); 15 antigen contact residues within 5 Å. An interactive 3D complex model is shown on this page. |
| Storage | Store at -20°C; avoid repeated freeze-thaw. Stable 1 year. |
| Advantages | Nanobodies are the smallest functional antibody fragments: exceptional thermal and chemical stability, single-domain, high-yield recombinant production, and access to cryptic epitopes and dense tissue that conventional antibodies cannot reach. |
