The P-gp drugs were identified through a literature review and classified according to substrate affinity, consisting of P-gp substrate, substrate/inhibitor, substrate/inducer, inhibitor, inducer, inhibitor/inducer and substrate/inhibitor/ inducer [ 5, 14– 16].
In the administration of their lands the brothers shared their estate managers and lawyers, while their local affinities consisted of the same gentry families.
Full-length RbbA was affinity-tagged at its C-terminal end by recombining a SPA (Sequential Peptide Affinity) cassette (consisting of a triple FLAG tag and a calmodulin binding peptide) into the chromosome [8].
An Escherichia coli expression vector for intracellular T7 promoter (PT7) driven production was constructed with an N-terminal dual affinity tag, consisting of a hexahistidyl (His6) tag in frame with the ZSPA-1 tag, thus allowing alternative affinity recovery methods.
The resultant plasma AChE was then incubated with an affinity matrix consisting of immobilized fasciculin-2 (Fas2-Sepharose; from from Latoxan, Valance, France), a polypeptide toxin from snake venom that binds with high affinity to the peripheral anionic sites of AChE [36].
The expression cassettes of the most successful vectors are based on a tandem affinity purification tag consisting of an octahistidine tag followed by the myosin motor domain tag.
To utilize iron from transferrin, ferritin or the environment, C. albicans uses a high affinity reductive pathway consisting of three steps.
Large buried surface areas within the protein-protein interfaces, and varying degrees of shape complementarity appear critical for modulating the stability of the multicomponent, low-affinity macromolecular complexes consisting of TCR, pMHC, CD8 or CD4, and CD3 gamma, delta, epsilon and zeta.
The family of currently known high affinity analogs consists of a diverse array of azacycles containing a basic amine.
A simple three-step protocol consisting of affinity purification of LBT/PTD dual-tagged proteins has also been developed, in which the proteins are purified by heparin-, then immobilized Ni2+-, and then heparin-affinity chromatography, in this order.
The functionality of the CspB moieties in the fusion proteins was assayed by their ability to bind with high affinity to an oligonucleotide consisting of seven deoxy-thymidines (dT7) [29], [29].
