Jenny:
Histology Control Systems, MasterTech, and Newcomer all offer
Helicobacter-in-Human-Stomach control slides.  All stain well with our
Warthin-Starry kit.  Sigma offer H. pylori "cultured" in human stomach, but
it was back-ordered, and Newcomer have Helicobacter in rat lung.
Take you pick.

Subject: Control Blocks or Slides


Hi, I am hunting for control blocks or slides containing helicobacter  and
blocks/slides for intestinal protozoa. Does the CDC still provide control
tissue? Is there a reliable vendor  source that someone out in Histoland
uses? Thanks In advance for all replies. Jenny
