What Makes A Good Antibody?

Boster Antigen design and expression overview

Design

We will design the antigen using our decades of experience in immunogen design, taking consideration of a variety of factors including sequence homology, post-translational modifcation, secondary/tertiary structure and epitope localization.

Expression

We recombinantly express the antigen with our proprietary protein folding technique to ensure best tertiary structure accuracy of the antigen to the target protein’s natural form.

Custom Antibody Service Overview

Standard package starting from $1300. Additional services cost see section "ADDITIONAL SERVICES".

Antigen

Recombinant antigen design

Immunization

Immunization of 2 rabbits

Purification

Affinity purification and validation

Deliveries

3-5mg antibody, ELISA test report

Additional Services

Pre-immune screening

Order a vial of pre-immune serum for screening existing immunity against the target protein, and for control purposes.*
Price: $100 per rabbit, 1ml of serum, not purified

Interim test bleeds

Order a vial of test serum after each of the immune booster shots to verify immune response’s antigen specificity and Ig isotypes.
Price: $50 per rabbit per bleed, 1ml of anti-serum, not purified

Additional rabbits

Order additional rabbits to improve the yield and success rate of your project. If the rabbit is positive and passes QC, 2mg of antibody will be added to your final deliverable.
Price: $200 per rabbit

Additional antibodies

If there are remaining antibodies from the batch, additional antibodies are available for purchase.
Price:
$150 for additional 100ug
$500 for additional 1mg
$1000 for additional 10mg (if available)

Blocking Peptide

If you require a blocking peptide for your developed antibody, we can help you with that.
Price: $150 for 1mg of blocking peptide

Recombinant Protein

If you want the recombinant protein we generated for you, you can purchase it from us.
Price: $200 for 1mg of purified recombinant protein. Inquire for bulk pricing.

Specific Application Insurance

Purchase an insurance for your antibody to work for certain applications.
Price: Custom, depending on the application and nature of the target protein

Intellectual Property & Exclusivity

If you intend to have exclusive rights for the produced antibodies, we can create a license that fits your needs.
Price: Custom, depending on the intended use of the antibody

*Why do I want pre-immune sera? Sometimes antibody immunization fails because some hosts have existing immunity towards your target protein of interest. This is especially common if the protein originated from organisms is related to common pathogens. Screening the hosts’ sera against your protein of interest can help mitigate this risk.

The Antibody Works Very Well

Boster Bio generated a custom antibody for zebrafish CDHR1a. The antibody works very well when used on cryosections in 5dpf+ old embryos.

The Staining is Clean

Antibody labels the retina outer segments and inner nuclear layers as expected based on in situ hybridization studies. The staining is clean.

Not sure what to place here

Used in whole mount IF on 24hpf zebrafish embryos. The signal is not precisely clean, but we do observe nlz2 expression in the ventral region of the retina as expected from in situ hybridization results.

This is a Very Good Antibody

Research of the lab aims to understand mechanisms of maternally deposited RNAs and proteins clearance during maternal-to-zygotic transition (MZT). This is a very good AB; tested on WB only. Image shows GFP-tagged Me31B.
