Application Areas

OriGene carrier-free antibodies are ready-to-use for various technologies that use conjugated antibodies as the core building element:

  • Fluorophore Conjugation: It has been widely used in many applications including fluorescence microscopy and flow cytometry. OriGene provides custom antibody conjugation services for various fluorophores and a conjugation kit for RPE.
  • Enzyme Conjugation: HRP or AP conjugated antibodies are used in applications like IHC, ELISA, or Western blot. OriGene provides HRP conjugation kit and custom services for this purpose.
  • Biotin Conjugation: The strong affinity of biotin-avidin is introduced in the downstream applications of the biotin-conjugated antibodies, which has been commonly used for the detection enhancement in Western blot, ELISA, or fluorescent microscopy. OriGene provides Biotin conjugation kit and custom service for antibody conjugation service.
  • Oligonucleotide Conjugation: Multiplex IHCs using cyclic detection protocols conjugate a panel of antibodies with different coding oligonucleotides to obtain cellular spatial profiling data.
  • Heavy Metal Conjugation: The combined technology of flow-cytometry and time-of-flight mass spectrometry (CyTOF) or Mass spectrometry imaging (MSI) uses heavy-metals and metal-chelating polymers to conjugate antibodies to resolve single-cell proteomics.
