Example sentences for: isotypes

How can you use “isotypes” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • All of the five monoclonal antibodies were of IgM isotypes (Table 1).

  • Th1 and Th2 cytokines regulate PG-specific autoantibody IgG isotypes and susceptibility to arthritis.

  • One of the major cellular serine/threonine protein phosphatases is protein phosphatase type 1 (PP1) [ 1 ] . An abundant enzyme expressed in all cells, complex regulation of PP1 is thought to be essential for proper temporal and spatial regulation of PP1 catalytic activity towards individual substrates [ 2 ] . Three different isotypes of the catalytic subunit, designated PP1α, PP1δ, and PP1γ1, are expressed in many different cell types [ 3 ] . Studies employing many eukaryotic systems all point to a crucial role for PP1 activity in controlling cell cycle progression, and an absolute requirement of this activity for mitotic exit [ 4 5 6 7 ] . There is also evidence to suggest that phosphorylation of PP1 and its associated proteins by the cyclin-dependent kinases may regulate PP1 activity in a cell cycle stage-dependent manner [ 8 9 10 ] . Hence, current efforts are directed towards identification of cell cycle-dependent substrates for PP1, and how regulation of PP1 activity towards these substrates controls the cell division cycle.

  • We did not measure potential differences in guinea pig IgG isotypes.

  • For example, paclitaxel-resistant lung cancer cells and ovarian tumors were shown to have increased levels of tubulin isotypes, particularly β-tubulin classes III and IVa [ 28 ] . Furthermore, when paclitaxel-resistant lung cancer cells were treated with antisense oligonucleotides for β-tubulin class III, the drug resistance was partly reversed, coincident with decreased protein levels of β-tubulin class III [ 65 ] . However, it should be noted that β-tubulin classes I, II, III, and IVa all increased significantly in paclitaxel-resistant lung cancer cells, indicating that the drug effect did not uniquely involve a single tubulin isotype.
