T and B Cell-based ELISA Assay

A most elaborate study on epitope analysis can provide detailed information on the peptides in a protein antigen directly associated with T cell recognition and antibody binding. Using the versatile ELISA assay, Creative Biolabs offers cancer epitope analysis service by detecting the cytokines released by epitope-specific immune cells.

Enzyme-linked Immunosorbent Assay (ELISA) for Cytokines Test

Cytokines are soluble proteins of polypeptides or glycoproteins that are secreted by immune cells, including neutrophils, monocytes, macrophages, B cells, and T cells at a certain period, to modulate immune responses to stimulus. Enzyme-linked immunosorbent assay is the gold standard of immunoassays in the measurement of cytokines in plasma and cell cultures. The assay is based on antigen-antibody-specific binding and enzymatic reactions conjugated to the detection antibody.

Work Steps of Sandwich ELISA

Protocol for sandwich ELISA. (Lin, et al., 2016)Fig.1 Protocol for sandwich ELISA.1

  • Fixed capture antibody on a solid plate
  • Add cell supernatant
  • Add enzyme-labeled detection antibody
  • Removing unbound enzyme conjugate and added substrate
  • Detect signals by spectrophotometry
