Nano-CaptureLigand human Ig, lambda

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

Applications

  • Detection and quantitation of human Ig lambda light chain antibodies and their antigens
  • Characterization of human Ig lambda antibodies’ binding kinetics and affinity
  • Human Ig lambda antibody discovery and screening in crude liquids like hybridoma supernatant, serum, and plasma
  • Epitope binning

The next level of antibody immobilization to BLI and SPR biosensors

  • 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
  • Human Ig lambda subclass specificity allows the application of a broad range of detection antibodies 
  • High affinity for strong immobilization of human Ig lambda antibodies even at low antibody concentrations

 

Comparison of ELISA immobilization methods

Nano-CaptureLigands are comprehensively validated

  • Characterized: DNA and protein sequences, affinity, melting temperature
  • Recombinantly produced, virtually without lot-to-lot variation
  • Manufacturing process is animal free
