Summary and Explanation:
Spirochete (Treponema pallidum) is the causative agent of syphilis. In the past,
localization of the spirochete agent was achieved with silver stains such as Steiner's
and/or Warthin-Starry. Treponema pallidum can now be successfully localized with
immunohistochemical techniques in formalin-fixed paraffin-embedded tissue. Studies
have shown this offers a substantial advantage over silver-techniques in both sensitivity
and specificity. The antibody consists of a rabbit purified IgG fraction and is highly
specific for spirochete (1).
Principle of Procedure:
Antigen detection in tissues and cells is a multi-step immunohistochemical process.
The initial step binds the primary antibody to its specific epitope. After labeling the
antigen with a primary antibody, an enzyme labeled polymer is added to bind to the
primary antibody. The detection of the bound antibody is evidenced by a colorimetric

Pretreatment Protocol:
Heat Retrieval Method:
Retrieve sections under pressure using Biocare's Decloaking Chamber, followed by a
wash in distilled water; alternatively, steam tissue sections for 45-60 minutes. Allow
solution to cool for 10 minutes then wash in distilled water.
Protein Block (Optional): Incubate for 5-10 minutes at RT with Biocare's Background
Primary Antibody: Incubate for 30 minutes at RT.
Probe: N/A
Polymer: Incubate for 30 minutes at RT with a secondary-conjugated polymer.
Chromogen: Incubate for 5 minutes at RT with Biocare's DAB - OR - Incubate for 5-7
minutes at RT with Biocare's Warp Red.
Counterstain: Counterstain with hematoxylin. Rinse with deionized water. Apply
Tacha's Bluing Solution for 1 minute. Rinse with deionized water.
intelliPATH™ Automated Slide Stainer:
IPR135 is intended for use on the intelliPATH™ Automated Slide Stainer. Refer to the
intelliPATH Automated Slide Stainer manual for specific instructions on its use. When
using the intelliPATH, peroxide block with intelliPATH Peroxidase Blocking Reagent
(IPB5000) may be performed following heat retrieval.
Protocol Recommendations (ONCORE Automated Slide Staining System):
OAR135 is intended for use with the ONCORE Automated Slide Staining System.
Refer to the ONCORE Automated Slide Staining System User Manual for specific
instructions on its use. Protocol parameters in the ONCORE Automated Slide Stainer

Technical Note:
This antibody has been optimized for use with Biocare's MACH 4 Universal HRPPolymer Detection and ONCORE HRP and AP Detections. Other Biocare polymer
detection kits may be used; however, users must validate incubation times and
protocols for their specific application. Use TBS for washing steps.
This product is provided for Research Use Only (RUO) and is not for use in diagnostic
procedures. Suitability for specific applications may vary and it is the responsibility of
the end user to determine the appropriate application for its use.
1. This antibody contains less than 0.1% sodium azide. Concentrations less than 0.1%
are not reportable hazardous materials according to U.S. 29 CFR 1910.1200, OSHA
Hazard communication and EC Directive 91/155/EC. Sodium azide (NaN3) used as a
preservative is toxic if ingested. Sodium azide may react with lead and copper
plumbing to form highly explosive metal azides. Upon disposal, flush with large
volumes of water to prevent azide build-up in plumbing. (Center for Disease Control,
1976, National Institute of Occupational Safety and Health, 1976) (2)
2. Specimens, before and after fixation, and all materials exposed to them should be
handled as if capable of transmitting infection and disposed of with proper precautions.
Never pipette reagents by mouth and avoid contacting the skin and mucous membranes
with reagents and specimens. If reagents or specimens come in contact with sensitive
areas, wash with copious amounts of water. (3)
3. Microbial contamination of reagents may result in an increase in nonspecific
4. Incubation times or temperatures other than those specified may give erroneous
results. The user must validate any such change.
5. Do not use reagent after the expiration date printed on the vial.
