Experimentation kits, introduction to plant cell culture

Catalog Number: (EDVO908)
Supplier: EDVOTEK EUROPE LTD
Description: Genetic modification of plants is a controversial area of biotechnology. All such experiments in plants begin with establishing plant cells in culture. This involves de-differentiating plant cells to form plant 'stem cells'. In this experiment, students establish cell cultures of African violets from leaves. They then use plant growth regulators to encourage root growth from the cultured cells, and produce a mature plant.

Experimentation kits: biodiversity study and biomass analysis

Catalog Number: (BE-403)
Supplier: G-Biosciences
Description: 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.

Experimentation kit, bioremediation by oil eating bacteria

Catalog Number: (EDVO956)
Supplier: EDVOTEK EUROPE LTD
Description: Oil spills cause devastation to the environment, killing sea life, birds, and coastal plants. Spraying areas of contamination with oil-eating microbes accelerates the degradation of the oil. This process is known as bioremediation. In this open-ended experiment, students grow a mixture of oil-eating bacteria and observe their effectiveness at degrading a variety of oils.

Experimentation kits, hydrophobic and hydrophilic proteins

Catalog Number: (BE-404)
Supplier: G-Biosciences
Description: This lab activity is designed to demonstrate the different classes of protein molecules and their classification based on solubility. Students learn fractionation of soluble, insoluble membrane proteins, and cytoskeleton proteins from a tissue sample. The insoluble protein fraction is further fractionated into hydrophilic and hydrophobic membrane proteins. Cell membrane structure and the role of hydrophobic membrane proteins are considered. This lab activity also provides an opportunity to understand characteristics of various classes of detergents and the role of detergents in solubilisation of hydrophobic membrane proteins.

Supelco® TraceCERT® Organic Reference Standard, Prothiofos

Catalog Number: (40799-50MG)
Supplier: Merck
Description: Prothiofos is a non-systemic insecticide and belongs to the group of organophosphates. It is an acetylcholinesterase (AChE) inhibitor causing hyperexcitation and impedes the functioning of the nervous system. Prothiofos gets activated by contact and ingestion and is used to control caterpillars <i>Pseudococcus spp</i>. thrips cockchafer larvae cutworms etc. in vegetables fruit maize sugar cane sugar beets tea tobacco and ornamentals. According to the Commission Implementing Regulation (EU) No 2076/2002 of 20th November 2002 prothiofos is not approved for use in the European Union (EU) as a plant protection agent following Regulation (EC) No. 1107/2009. But a default maximum residue limit of 0,01 mg/kg is applicable for the presence of prothiofos in products of plant and animal origin according to Art 18(1)(b) Reg 396/2005.

Supelco® TraceCERT® Organic Reference Standard, Chlorimuron Ethyl

Catalog Number: (06846-50MG)
Supplier: Merck
Description: Chlorimuron-ethyl is a member of sulfonylurea herbicides used wildly for pre- and post-emergence control of broad-leaved weeds in soybeans maize peanuts beans and other crops. It is characterised by very low application rates high herbicidal activity good crop selectivity and low toxicity. Chlorimuron-ethyl is an acetolactate synthase (ALS) inhibitor that acts by inhibiting the biosynthesis of the essential amino acids like valine leucine and isoleucine. This stops the plant growth as cell division of growing roots and shoots tips are inhibited.

Experimentation kits, physical properties of proteins

Catalog Number: (BE-401)
Supplier: G-Biosciences
Description: The physical properties of proteins kit is a lab activity that enables students to investigate the physical properties of several different proteins. Students will learn about protein solubility and how it is affected by various parameters; including temperature, pH, salt and dielectric constant. They will understand about protein precipitation due to pH, high salt and in the presence of organic solvents and about protein denaturation as a result of high temperature. In addition, the kit will demonstrate how non-protein agents, such as detergents drastically alter the physical properties of protein molecules and as a result, understand the importance of detergents in protein solubilisation. This lab activity involves analysis of three different types of pure proteins and then students alter some of those properties with a detergent and re-examine physical properties of those proteins. Students are challenged to consider how physical properties of protein molecules can be exploited for purification and characterisation of proteins and apply their findings on a test sample of complex tissue extract.
