Polyclonal Antibody Generation

BioGenes is your expert for high-quality polyclonal antibody development services. Our dedicated team has developed more than 10,000 polyclonal antibodies for more than 30 years. We offer a variety of host species, and our immunization protocols ensure fast results, high yields, and a superior quality.

 

Development Strategy

Every polyclonal antibody development can be customized according to your specific needs and can cover any or all of the workflow steps — consultation, peptide or protein antigen production, antibody generation and purification – for a variety of applications, e.g. for the development of an ELISA.

Phase 1 - Expert consultation

  • Selection of species and immunization protocol

Phase 2 - Preparation of the immunogen

Phase 3 - Immunization

  • According to the selected species and protocol

Phase 4 - ELISA titer tests

  • Of pre-immune sera and antisera 

Phase 5 - QC & shipping

  • Of pre-immune sera and antisera, optional affinity purified antibodies

Approximate project duration: 5 weeks (high speed protocol for proteins). 

Extended protocols available.

Animals and Protocols

 

All animals used for polyclonal antibody generation are housed in certified facilities in Germany demonstrating our commitment and responsibility for animal welfare.

Rabbits

We offer different immunization protocols for antibody generation in rabbits, depending on whether antibodies are needed in a short time, highly specific or large amounts. Depending on the antigen (protein or peptide) and the requirements, our protocol lengths differ. The times and yields are shown in the following tables.

Protein Immunization Protocols
For the immunization of rabbits with proteins, we offer different strategies depending on the objective pursued. Certain protocols can be adapted in consultation with our scientists. The quality of the serum is always controlled by ELISA. After delivery of the antiserum the animals can be further kept if choosing the protein protocols High Speed, High Quality or High Yield.

High Yield Protein2 mg protein (≈1 mg/mL)1.5 mL pre-immune serum and approx. 60 mL antiserum per animal17 weeks
Complete & Easy Protein1.5 mg protein (≈1 mg/mL)1.5 mL pre-immune serum and approx. 90 mL antiserum per animal15 weeks

 

Peptide Immunization Protocols
Our scientists will assist you in the selection of the sequence and conjugation to a carrier protein. We recommend a sequence of 15 amino acids, which will be synthesized and purified by our collaborators. Immunization is carried out according to the following protocols and the customer's requirements. Each protocol also includes the delivery of 1.5 mL of pre-immune serum.

Mice

Immunization of mice is a cost-effective way to generate polyclonal antibodies if only small amounts of antiserum are required. We conduct a quality control of the antiserum using ELISA, if antigen is suitable. Immunization of mice with peptide antigens is possible upon request

 

ProtocolAntigen provided by the customerProducts sent to the customerExpected time frame
Standard protocol0.5 mg (≈ 1 mg/mL)0.2 - 0.4 mL antiserum per animal42 days

Rats

Immunization of rats leads to higher amount of antiserum compared with mice and is still fast and cost effective. We conduct a quality control of the antiserum using ELISA, if antigen is suitable. Immunization of rats with peptide antigens is possible upon request

Standard protocol0.5 mg (≈ 1 mg/mL)2 - 4 mL antiserum per animal42 days

Sheep & Goats

Immunization of goats or sheep lead to large amounts of antiserum and/or purified antibodies with manageable time frames and animal numbers. The immunization schedules can be modified according to your special requirements and the aim of your project. We conduct a quality control of the antiserum using ELISA, if the antigen is suitable. Animals will be kept after delivery of the antiserum.
