88 activities | biomedical technology Ward’s AIDS: The Discovery and Clinical Diagnosis of HIV by ELISA Lab Activity Safe Application of Immunological Deficiency Diagnostic Technique Students use the ELISA method and simulated blood serum to determine the HIV status of four individuals, applying the actual testing procedure used to detect AIDS antibodies in blood with materials that are completely safe. The simulated blood serum uses no human substances, eliminating any health risks. The lab activity can be completed in two 1-hour lab sessions. For a safe but realistic experience, the activities utilize real antigens and antibodies isolated from non-human sources; students don’t handle any human body fluids. Each lab activity comes with enough materials for six setups, a teacher’s guide, and student copymaster. Note: Includes perishable materials. Please specify delivery date. 853518 $97.85 One-Step Antibody ELISA for Diagnostics Lab Activity Complete This Lab In Half the Time of Traditional ELISAs With this time-saving kit, an antigen, such as a viral bacterial or a human cancer marker is recognized by an antibody to which an enzyme is covalently linked. In the presence of the substrate, a color product is produced. This one-step process eliminates time-consuming steps of traditional ELISA labs where a two-step molecular binding event is necessary. This innovative activity allows you to recognize a link faster and easier. The whole lab can be completed in 30 minutes. Includes materials for 10 setups and a teacher’s guide with complete instructions, background information, and study questions. Note: Includes perishable materials. Please specify delivery date. 853520 $99.00 Simulation of HIV Detection by Western Blot Lab Activity Perform the Same Procedure Used in Labs to Detect HIV Antibodies, in Complete Safety The Western blot test, an analysis of polypeptides and proteins, is used as a “second generation” immunoassay on samples that have tested positive for HIV antibodies. Now students can analyze polypeptides and proteins, utilizing the Western blot test in a lab activity that’s suitable for advanced high school and college classes. Best of all, the lab activity does not require the use of real blood. The lab activity, which can be performed using agarose gel electrophoresis, can be completed in two 90 minute lab sessions, and it comes with enough materials for up to five blots, a teacher’s guide, and student copymaster. An agarose electrophoresis chamber, power supply, and 20 mL micropipets, all required, are available separately. Note: Includes perishable materials. Please specify delivery date. 368559 $115.09 How Does a Doctor Test for Lyme Disease Lab Activity Perform an ELISA Test Introduce students to an immunology-based diagnostic test used to detect various infectious diseases, including Lyme disease. After completing an ELISA test on control and simulated samples, the infected patients are identified. Includes materials for six experiments. 368907 $59.95 Clinical Diagnostic Immunoblot Lab Activity Simulation of Clinical Diagnostic Techniques Immunoblot, otherwise known as dot blot, is a technique used to determine the presence of an antigen. In this experiment, antigens are absorbed to a membrane that is then treated sequentially with an antigen-specific antibody solution and a secondary antibody conjugated to an enzyme. The enzyme-substrate reaction generates a color product that precipitates on the membrane, indicating a positive reaction. This process highlights how clinical diagnostic kits employ the principles of the immuno-blot. No human serum is used in this experiment. Includes materials for six setups. Note: Contents are shipped ambient, some components require storage at 4°C. Note: Includes perishable materials. Please specify delivery date. 368959 $115.90 Antibody-Antigen Interaction Lab Activity Immunodiffusion Procedure Makes Results Easy to Visualize The interaction between antigens and antibodies is vital to all aspects of immunology, and this handy activity clearly demonstrates that relationship. Students employ the Ouchterlony Procedure to demonstrate the formation of an antigen-antibody complex through passive diffusion, resulting in an easily observed precipitate in the diffusion medium. For a realistic yet safe experience, the activity utilizes antigens and antibodies from animals; no human components are used. It includes materials for ten setups and instructions. Note: Includes perishable materials. Please specify delivery date. 368540 $108.15 1.800.932.5000 | vwr.com
iomedical technology | activities 89 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. Redeem by mail, fax, phone, or e-mail. 366009 $191.00 DNA Depot Simple, Student-Directed <strong>Science</strong> Activities • Designed to highlight fundamental science concepts without the use of expensive reagents and equipment • Students come away with a greater understanding of science, technology, and their role in society • All experiments are created and classroom tested by teachers and science education experts • Each kit includes an experiment guide with background information, procedures, safety recommendations, and an evaluation quiz 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. 368942 $118.15 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. 368941 $70.00 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. 368920 $48.00 ward’s science+
