Donkey Polyclonal Antibody Production Service

KMD Bioscience has been working on producing polyclonal antibodies for many years. Based on our mature antibody system and advanced technology, we can offer comprehensive polyclonal antibody production services include production of polyclonal antibodies in mouse, rat, rabbit, and other species. Meanwhile, we can accept various antigens for polyclonal antibody production such as small molecules, peptides, modified peptides, proteins, fusion proteins, modified proteins, etc.

KMD Bioscience has experienced immunology experts, standard operating procedures, and standard animal facility, which can provide first-class antibody products and technical services to scientists and researchers. We promise to provide high-performance donkey polyclonal antibody production services and related testing services. Moreover, we can ensure the ELISA titer of the positive antisera & antibody can reach 1:50,000 and ensure the western blot results for protein antigens.


Service Process:



Service Content:






1. Clients provide the antigens (small molecules, peptides, proteins); Purity>85%,, concentration>0.5mg/mL, ~2mg

2. Immunize one donkey, 5 boosts, ELISA titer determination

3. Negative control: pre-immune serum collection before the first immunization, 1mL

4. Serum harvest and ELISA titer determination

5. Deliver ELISA report, 1mL pre-immune serum and 250-500mL antisera to investigators

12-14 weeks

Consecutive bleed

1. Inject 500ug antigen mixed with 0.5mL Freund's incomplete adjuvant per donkey

2. 100-150mL blood is collected after every two weeks and ELISA titer determination.

3. Ship the product & reports to investigator to test the serum and determine the quality of the antibodies.

2-3 weeks/phase

Total bleed

1. Collect all the blood and the donkey is humanely euthanized.

2. Serum collection, provide the products according to investigator’s requirements

1-2 weeks


1. Purify the donkey sera by DEAE or affinity chromatography

2. Deliver the purified polyclonal antibody to investigators

1 week


Besides, we can provide the following antibody services:

*Antibody Identification: ELISA, WB, IF, IP, IHC, SPR, etc.

*Antibody Modification: Enzyme modification (HRP, AP, biotinylation), fluorescent labeling (FITC, FAM, etc.), fusion label (GST, His), magnetic beads labeling, quantum dot labeling, etc.
