ELISA Kit Development Service by Hokudo Co., Ltd

We support to develop a quantitative assay or detection method based on antigen-antibody reaction. We develop ELISA kit with normally your or commercially available antibody. Otherwise, we design recombinant protein expression, peptide synthesis, and antibody production to develop ELISA kit designed for your needs.

>> Request Form

Evaluation process: at least 4 weeks

Evaluation to see if we can develop an assay method on your request basis.

  • Antibody evaluation (capture and enzyme-linked antibody)
  • Assay method evaluation (sandwich and competitive ELISA)

Optimization process: at least 4 weeks

Determination of reaction condition to meet your requested assay range and sensitivity.

  • HRP-linked antibody preparation
  • Optimization of reaction condition
  • Performance test

Production process: at least 4 weeks

Components:
Antibody-coated plate, standard protein, enzyme-linked antibody, reaction buffer, substrate solution, stop solution and wash buffer.

*Required materials

  • Antibody (200 ug - 2 mg)
  • Antigen (50 - 500 ug)

Please note you might be charged as evaluation fee regardless of whether an assay kit eventually is developed completely or not.

Immunochromatography Assay Development Service by Hokudo Co., Ltd

Immunochromatography assay was developed for achieving simply and rapidly detection of a target protein. Because of visible result in a short period of time, the assay is suitable for the purpose of simplified screening or field research, such as influenza viruses test, food allergens test, etc.

>> Request Form

  1. A sample contained antigens puts on the Sample pad, and then immerses into a membrane by capillary phenomenon.
  2. Antigens react with enzyme-linked antibody while they follow, and then on Test line they react with coated antibody resulting in a visible line.
  3. The assay is done by captured enzyme-linked antibody by coated antibody on Control line resulting in a visible line.
