  • Immunohistochemistry Services

  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Custom Antibody Production Services

High quality rabbit polyclonal antibodies

LifeSpan offers full service production of rabbit polyclonal antibodies from peptide design to the characterization of the final product. With a decade of antibody production experience and more than 2,500 antibodies synthesized, LifeSpan can help you develop the reagent you need.

Investigators can quickly initiate the production of an antibody by selecting the LifeSpan SureAbTM Synthesis Service or work with LifeSpan to design a more customized protocol to suit their specific needs.

Production projects can be tracked in real time through LifeSpan’s secure online interface, allowing investigators to make adjustments as the protocol develops.

Once produced, antibodies can then be characterized for affinity and specificity by Western Blot analysis or in immunohistochemistry, taking advantage of LifeSpan’s expertise as a molecular pathology provider and extensive tissue bank.

SureAbTM Synthesis

The SureAbTM protocol has been designed to include those features that LifeSpan finds to be most effective in generating antibodies that are optimally sensitive and specific.

SureAbTM Synthesis Protocol

  • Peptide synthesis (10 mg at 95% purity)
  • Peptide conjugation to KLH (2 mg)
  • Duplicate rabbit immunization (13-weeks, 6 boosts)
  • 1 pre-bleed, 3 production bleeds (120 ml sera per rabbit pair)
  • 20 ml affinity-purification of the 1st production bleed

SureAbTM Options

  • LifeSpan peptide design
  • Number of peptides per target
  • Characterization by Immunohistochemistry
  • Characterization by Western Blot
  • Additional affinity-purifications

Antibody Characterization

The antibody characterization protocol for each study is custom designed to address the particular needs of the investigator. LifeSpan offers both Western Blot and Immunohistochemistry characterization using tissue and cell lines from its extensive tissue bank or supplied by the investigator.

Immunohistochemistry Analysis

  • Formalin-fixed and Frozen tissues
  • LifeSpan supplied normal and diseased human tissues
  • LifeSpan supplied mouse, rat, dog, and primate tissues
  • Commercial or client supplied tissues or cell lines

Immunogen Preparation 

  • Peptide design (LifeSpan experience)
  • Peptide synthesis (variable scale and purity)
  • Synthesis efficiency testing (HPLC, Mass Spec)
  • Peptide conjugation (KLH, BSA, Ovalbumin, other)
  • Conjugation efficiency testing (Gel shift assay)
  • Immunogen types (peptide, whole protein)


  • Number of animals immunized

  • Flexible immunization schedule
  • ELISA testing of bleeds
  • ELIAS testing for production of KLH antibodies

Post-purification Testing

  • Reducing and non-reducing gel
  • Bio-Rad Kit
  • 280/260 UV measurement

Antibody Purifications

  • Large and Small Scale
  • DEAE/IgG purification
  • Protein A/G preparation
  • Affinity purification
  • Acid/Base elutions

Column Types

  • SulfoLink column
  • Sepharose 4B/BSA column
  • SulfoLink/BSA/SMCC column
  • Affi-gel column

Protocol Flexibility

Having the ability to follow the real-time progress of an antibody production provides greater control over the project’s outcome. LifeSpan offers protocol flexibility so that changes can be made quickly to improve the rabbits immune response. Some changes that may effect outcome are:

  • Changing adjuvant
  • Double dosing
  • Variable point of injection 

Cost and time savings may also be gained by terminating non-responsive-projects early.

Supporting Products

LifeSpan also offers the following products and services in support of its antibody production service.

Service Deliverables

Upon completion of each antibody project, clients are supplied with affinity-purified antibody, unpurified antisera, peptides, the purification column, and a production report. Depending upon the terms of the agreement, this report will contain an overview of the production and details of the antibody characterization results with accompanying images.
