Molecular biology

A product of plant origin that converts hides into leather; often polyphenols and aldehydes that cross-link collagen chains and render them insoluble and unreactive to enzymes that would degrade and ...

Spare receptors

Biology; Biochemistry

The phenomenon of a hormone-responsive cell having more receptors capable of binding the hormone than are needed to effect a maximal response; possibly an adaptation that makes the cell responsive to ...

Expression cloning

Biology; Biochemistry

As part of a repetitive process for screening a library, the sampling of cells according to the presence of the product of the gene of interest, e.g. the identification of the glutamate receptor in a ...

Seven transmembrane domain protein (7TM)

Biology; Biochemistry

One of a group of structurally related long polypeptide chains which possess seven α-helical domains that span a membrane, the intervening intra- and extracellular loops which connect them, and the ...

Manton-Gaulin homogenizer

Biology; Biochemistry

An apparatus for disruption of cells, especially the large quantity of bacteria or yeast that result from a fermentation, by pumping a paste of the collected cells through an orifice of adjustable ...

Signature sequence tag (SST)

Biology; Biochemistry

One of a set of short DNA sequences for which probes are available for the identification of a gene. As the combination of 600 to 1500 SSTs provide a unique signature for any gene, such probes can be ...

Linking number (L)

Biology; Biochemistry

A topological property of double-stranded DNA; the number of right-handed turns one DNA strand makes around the other. For relaxed DNA the number is equivalent to what it would be for linear, ...
