Biology > Introductory Biology Email this pageVideo Lectures - Lecture 15/nTopics covered: Bacterial Genetics Instructor: Prof. Graham Walker Transcript - Lecture 15/nSo in this last lecture, what I'd like to do is I'd like to now begin to talk about genetics. And when we talked early on in the semester I was showing you this way that you can study biological function. Biochemists, for the m...

The conjugation of polyclonal and monoclonal antibodies with fluorescein isothiocyanate (FITC) is used in immunohistochemistry and immunofluorescence studies. FITC isomer I is a widely used fluorescent labeling reagents due to the fluorophores high quantum efficiency and conjugate stability.

Antibodies labeled with biotin provide the user with a tool for increasing the sensitivity of an assay by its ability to amplify a given reaction. A biotin/streptavidin (avidin) system offers low background, enhanced sensitivity and the ability to detect minute amounts of antigens.

The humoral immune response B-cells (so-called because they mature in the bone marrow) are white blood cells that work chiefly by producing soluble substances known as antibodies. Each B cell is programmed to make one specific antibody. When a B cell encounters its specific or eliciting antigen (along with various accessory cells), it differentiates into a plasma cell. The latter is essentially a...

Subclones: Transcript The clone libraries were prepared using bacterial artificial chromosomes, or BACs. Each BAC clone contained 100,000 to 200,000 bases of DNA sequence. The large BAC clones were used to establish the order of the DNA sequences. To sequence the DNA, smaller-sized clones were needed. Project scientists cut the large BAC clones into smaller fragments of about 2,000 bases. These s...

This video explain plasmid cloning. I am also adding here background information: Plasmids are circular, double-stranded DNA (dsDNA) molecules that are separate from a cell's chromosomal DNA. These extrachromosomal DNAs, which occur naturally in bacteria, yeast, and some higher eukaryotic cells, exist in a parasitic or symbiotic relationship with their host cell. Plasmids range in size from a few ...

Microbial populations achieve genetic diversity through horizontal gene transfer. Bacteria may transfer genes from one to another by conjugation, transformation, or transduction. Scientists often exploit these processes through recombinant DNA

In molecular biology, Transformation is the genetic alteration of a cell resulting from the uptake and expression of foreign genetic material (DNA). Separate terms are used for genetic alterations resulting from introduction of DNA by plasmid-encoded conjugation or by viruses (transduction). Transformation of animal cells is usually called transfection. The term transformation is also used more...

HFR strain A strain, or clone, in which a conjugative plasmid (such as an F'), integrated in the bacterial genome, is instrumental in the transfer (along with plasmid DNA) of integrated bacterial DNA in a sequential manner to a suitable recipient.
