Descripción: Biodiversity lab activity is designed for determination of protein contents and biomass in diverse biological samples to study how biomass is related to biodiversity in nature. Students collect and catalogue plant leaf samples from a diverse group of locally available plants. This lab activity involves determination of natural weight of each plant sample, grinding a predetermined amount of each sample, and the subsequent extraction of proteins from the samples. Students then learn to determine protein contents of each plant sample and attempt to relate the protein content with biomass. Students in this lab activity are challenged to think, analyse, and seek answers as to why protein biomasses vary for a given natural weight for different plants. Finally, they will relate that finding to the biodiversity of nature.

Descripción: A major challenge for molecular biologists and genetic engineers is to easily detect and analyze genetic mutations that occur naturally, causing diseases, or during genetic engineering or cloning, whether deliberate or accidental. Students learn about different types of genetic mutations, including substitutions, deletions and point mutations and about various techniques used to detect genetic mutations. The kit contains all the reagents to screen simulated clinical samples for a mutant gene, using both the polymerase chain reaction (PCR) and restriction digestion mapping. Students conduct a simple clinical diagnostic experiment in order to identify a diseased patient.

Descripción: In this lab activity, students learn to perform carefully controlled experiments to generate protein fragments using a proteolysis enzyme and then analyse the protein fragments by electrophoresis. By analysis of protein fragmentation patterns, i.e. protein fingerprints, students learn about protein sequence, structure, and their conservation. Students resolve a set of three functionally identical protein samples selected from throughout the animal kingdom; including human, bovine and sheep. After generating fingerprints by electrophoresis, students examine the protein fingerprint of each sample to determine the degree of conservation.

Descripción: Standard agarose is a purified linear galactan hydrocolloid isolated from agar or agar-bearing marine algae with an Electroendoosmosis (EEO) value of 0.12 making it an essential component in chemical separation techniques.
Standard agarose is a very low electroendosmosis agarose (EEO) which is recommended for sharp resolution of nucleic acid fragments greater than 400 bp and up to 8000 bp. This Standard Agarose may be used at concentrations between 0.8 % and 2 %. Southern and Northern transfers can be performed efficiently from them.

Descripción: Over 30% of the world's population uses tobacco products, and 90% of that is from cigarettes. The physical effects of nicotine and the diseases it can cause, including cancer, are detailed on this anatomical poster. For such a wide spread practice education is important and this anatomy poster can help do that. This thickly laminated anatomical chart is printed on premium glossy (200 g) UV resistant paper and comes with two sided lamination (125 µm, 5,0 mil) and metal eyelets to make the chart easy to display.

Descripción: Using the Protein Electrophoresis kit, students will learn the principles of various types of electrophoresis, including denaturing and non-denaturing electrophoresis, and how this powerful technique is used to analyse proteins. The kit will introduce students to the different separation matrices currently in use and will understand their differing separation properties and their role in protein analysis. Students have an option of casting their own electrophoresis gels using polyacrylamide or using pre-cast commercially available gels. This kit is provided with all of the reagents, buffers and supplies needed for casting acrylamide gels, preparing protein samples, running electrophoresis, and staining the gels for visualisation of protein bands. Test protein samples and protein standards are also provided.

Descripción: An HIV test detects HIV infection indirectly using an ELISA test against HIV antibodies in the blood. The test works by taking antibodies from the patient's blood and adding them to a microtitre plate coated with HIV antigen. If HIV antibodies are present, they will bind to the antigens on the plate. In this experiment, students perform an ELISA text by coating microtitre plate wells with simulated HIV antigen and then test simulated donor serum for anti-HIV antibodies.

Descripción: Coronary heart disease and stroke are major causes of death in the Western world. Elevated blood cholesterol levels are a serious risk factor in both conditions. The genetic disease familial hypersholesterolemia (FH) causes an increase in blood levels of the bad form of cholesterol, low density lipoprotein (LDL). In untreated patients with the mutant FH gene, the condition can cause premature death. This experiment introduces the colorimetric enzymatic reaction which is the basis of the clinical cholesterol test. In addition, using agarose gel electrophoresis, students can analyse a simulated genetic screening for a disease.

Descripción: This lab activity has two objectives - to deepen the understanding of protein molecules and for students to learn the potential of electrophoresis in protein analysis. Students study the fundamentals of protein structure from their primary structure to the more complex tertiary and quaternary structures, utilising protein electrophoresis. Complex mixtures of protein samples and characterised pure protein samples, in conjunction with electrophoresis, are utilised to study protein structure and the potential of protein electrophoresis. Using non-denaturing and denaturing electrophoresis, students understand the difference between primary, tertiary and quaternary structures, the importance of disulfhydryl bridges in maintaining protein structure and electrophoresis in studying complete proteins and protein subunits.
