Experimentation kits, introduction to plant cell culture

Codice catalogo: (EDVO908)
Fornitore: EDVOTEK
Codice articolo fornitore: 908
Codice articolo locale: EDVO908
Descrizione: 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

Codice catalogo: (BE-403)
Fornitore: G-Biosciences
Codice articolo fornitore: BE-403
Codice articolo locale: GENOBE-403
Descrizione: 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

Codice catalogo: (EDVO956)
Fornitore: EDVOTEK
Codice articolo fornitore: 956
Codice articolo locale: EDVO956
Descrizione: 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

Codice catalogo: (BE-404)
Fornitore: G-Biosciences
Codice articolo fornitore: BE-404
Codice articolo locale: GENOBE-404
Descrizione: 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.

Codice articolo locale: SUPL06846-50MG
Descrizione: 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.
