Nano-CaptureLigand human Ig, lambda

4
Description
The Nano-CaptureLigand™ human Ig, lambda-LC captures and immobilizes human Ig lambda light chain (LC) antibodies to avidin/streptavidin coated surfaces used in BLI, SPR, and ELISA assays. It consists of a biotinylated Nanobody that specifically binds to human Ig lambda LC antibodies with high affinity and in a site-directed manner.
Specificity: Lambda light chain of human Ig lambda antibodies
Nano-CaptureLigands specificity overview
Conjugates: Biotin
Applications
Human Ig lambda capture to biosensors used in BLI and SPR
Human Ig lambda immobilization for ELISA
Advanced immobilization of antibodies
Specific, stable, and site-directed immobilization of non-biotinylated human Ig lambda antibodies to streptavidin/avidin

Product Type
Capture Nanobody (VHH)
Applications
Immobilization of human Ig lambda-LC antibodies on avidin and streptavidin surfaces for Bio-Layer Interferometry (BLI), Surface Plasmon Resonance (SPR), and ELISA
Target/ Specificity
Lambda-LC of human Ig lambda antibodies
Cross-reactivity
No cross-reactivity to human Ig kappa; goat IgG; mouse IgG; rabbit IgG Fc; rat IgG
Cross-reactivity to rabbit IgG Fab
Affinity (Kd) of monovalent (1:1) binding mode
0.1 nM
Apparent affinity may be higher for full IgGs due to avidity effects (1 antibody captured by 2 Nanobodies).

- Site-directed and specific immobilization of the Fab-fragment of human Ig through the lambda light chain to streptavidin coated biosensors without biotinylation of the antibody
- Compatible to surface plasmon resonance (SPR) and biolayer interferometry (BLI) assays (e.g. FortéBio Octet® systems)
- High affinity for stable baseline without significant dissociation
- >10x regeneration for multiple reuse
- High specificity enables human Ig lambda antibody discovery and screening in crude liquids like hybridoma supernatant, serum, and plasma samples
The next level of antibody immobilization for ELISA
- Compatible to enzyme-linked immunosorbent assays (ELISA)
- Site-directed immobilization of human Ig lambda light chain antibodies to streptavidin/avidin coated surfaces of sandwich ELISAs without biotinylation of antibody
- Combine the site-specificity of protein A, G, and L with the stability of the biotin/streptavidin interaction
