Abnova offers high quality, efficient and cost-saving conjugation service between antibody and fluorescent dyes, phycobiliproteins, streptavidin, biotin and enzymes. Since every antibody has its own unique characteristics, conjugation needs to be optimized. 0.2mg of total antibody of interest will be tested and analyzed prior to mass labeling. The tested sample will be mixed with mass conjugate product for final purification. We will complete the conjugation within 2-3 weeks from the time we receive the antibody sample.

Special Notes:
  1. The antibody of interest should not contain albumin, gelatin, or other amine-containing stabilizers. Purification of antibody from ascites fluid, serum, or cell culture medium or removal of stabilizer proteins prior to conjugation will result in additional cost to the customer.
  2. Minimum quanity of antibody conjugation is 0.2mg. Minimum concentration is 0.1mg/ml.
