Ward’s Karyotyping Human
Chromosomes Lab Activity
Safely Explore Actual Human Chromosomes
Examining the banding patterns on chromosome spreads helps determine
several factors in humans, such as a person’s sex, and any abnormalities that
may be present, such as Down, Turner, and Klinefelter Syndromes. Ideal for
advanced high school and college classes, students prepare, stain, and study
an actual human chromosome spread to observe the banding patterns. For
greater convenience, the human cells supplied in the activity come fixed at the
metaphase stage. The cells are captured at a point of maximum contraction
during mitosis, making the banding patterns clearly visible. The lab activity can
be completed in two 45-minute lab sessions, and it comes with enough materials
for six setups, a teacher’s guide, and student copymaster. An incubator,
optional, is available separately. Note: Coupon included for perishable materials.

Analysis and Comparison of
Mamalian Cell Types Lab Activity
Includes Cell Samples Safe for Classroom Use
Differences between various mammalian cell types and how these cells function
are revealed in detailed magnification with this activity. Cells are fixed on
microscope slides, after which students stain the cells on the slide to view morphological
characteristics of diverse cell types. The lab can be completed in 35
minutes. Includes materials for six student groups, instructions, multispot slides,
eosin and methylene blue stain, mounting media, cover slips, transfer pipets,
and immersion troughs. A microscope with 400X magnification is required, but
not included.

Blood Based
Cancer
Diagnosis
Lab Activity
Observe the Reaction
of Cancer Cell Markers
and Their Corresponding
Antigens
Cancer cells differ from normal
cells by the combination
of normal proteins that are
present on their surfaces.
Antibodies against these proteins
will specifically bind to
cancer cells, but not to normal
cells. This characteristic
allows for early detection of
cancer and potentially a way
of delivering cancer therapies.
In this experiment, students
view this process first-hand
and understand the basis
of cancer diagnosis. The lab
takes 35 minutes to complete
and materials for 10 student
groups are provided. Includes
instructions, microtiter plates,
cancer cell markers, normal
cell markers, transfer pipets,
and buffer.

What is Cancer? Lab Activity
A large number of cancers have been identified by association with the
various parts of the human anatomy. In this experiment, fixed normal
and cancer slides will be provided for students to conduct basic microscopy
and determine the basic differences in cell structure. Emphasis is
placed on skin cancer, which can easily be controlled by limiting exposure
to sun. A basic microscope is required. Includes six slides.
