Enzyme-Linked Immunosorbent Assay01:33

Enzyme-Linked Immunosorbent Assay

17.6K
In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen.  Enzyme-substrate reaction allows the antigen to be visualized or...

Responses to Salt Stress

14.5K
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Osmoregulation in Insects

17.6K
Malpighian tubules are specialized structures found in the digestive systems of many arthropods, including most insects, that handle excretion and osmoregulation. The tubules are typically arranged in pairs and have a convoluted structure that increases their surface area.

Plant Breeding and Biotechnology

21.7K
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Social Exchange Theory02:06

Social Exchange Theory

40.8K
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Translesion DNA Polymerases02:10

Translesion DNA Polymerases

11.2K
Translesion (TLS) polymerases rescue stalled DNA polymerases at sites of damaged bases by replacing the replicative polymerase and installing a nucleotide across the damaged site. Doing so, TLS allows additional time for the cell to repair the damage before resuming regular DNA replication.
TLS polymerases are found in all three domains of life - archaea, bacteria, and eukaryotes. Of the different classes of TLS polymerases, members of the Y family are fitted with specialized structures that...

  • To provide a standardized protocol for assessing desiccation survival in Acinetobacter baumannii.
  • To enable comparative analysis of different bacterial strains under varying environmental conditions.

Main Methods:

  • The chapter details a protocol for evaluating bacterial survival after exposure to dry conditions.
  • This method allows for controlled manipulation of environmental factors influencing desiccation stress.

Main Results:

  • The protocol facilitates robust comparisons of desiccation survival rates among Acinetobacter baumannii strains.
  • It accounts for the multifaceted nature of desiccation as a stressor.

Conclusions:

  • The presented protocol is essential for accurately assessing and comparing the desiccation tolerance of Acinetobacter baumannii.
  • This will aid in understanding and mitigating the pathogen's persistence in healthcare environments.
