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.

The Mammalian β-Galactosidase Assay Reagent Kit is a simple and versatile assay to measure β-galactosidase activity in cultured mammalian cells. Cells grown on a plate may be lysed and tested for β-galactosidase activity by adding a single all-in-one lysis-and-assay solution. Alternatively, M-PER™ Mammalian Protein Extraction Reagent may be used to prepare lysate from washed adherent or pelleted cells, and then a portion of the lysate used to assay for β-galactosidase activity. With M-PER Reagent, there is no need to scrape cells or to perform freeze-thaw cycles. The remaining lysates prepared with M-PER™ Reagent may be used for applications such as reporter assays (luciferase, β-galactosidase and chloramphenical acetyltransferase), protein kinase assays (PKA, PKC, and tyrosine kinase), immunoassays (Western blot, ELISA, RIA) and protein purification.

Determination of protein concentration is an essential technique in all aspects of protein studies and proteomics. The Assays for Protein Quantification kit includes three of the most widely used protein assays and allows for a direct comparison of the three assays that teaches students the benefits and limitations of each assay. Each assay is available individually to allow teaching of a specific assay, without the option of comparing and contrasting with other assays. The three assays covered are the Biuret Protein Assay, Lowry Protein Assay and the Coomassie Blue Dye Protein Assay. The Assays for Protein Quantification kit provides all the reagents required to perform both protein assays, including protein standards for accurate quantification, in a single lab activity. An often underestimated factor in quantifying protein is the presence of non-protein interfering agents, such as salts and detergents. This kit teaches students about common laboratory agents that affect the protein assays, the reasoning behind their interferences and how to overcome the interference. Students also learn how to select a protein assay for different applications.
