30s loop

Another method for estimating thixotropy involves the hysteresis of the thixotropic loop. The area of the thixotropic loop is calculated or measured, which works well with printing inks (3). In a variation of this method, the up curve on an undisturbed sample is deterrnined. The sample is then sheared at high shear (>2000 ) for 30—60 s, followed by deterrnination of the down curve (22). The data ate plotted as Casson-Asbeck plots, vs 7 / (14), as 

One glycosylation site exists on the P suburhts of human LH [53664-53-2 and TSH [64365-92-OJ ie, Asn-30 (Fig. 4). In some species, Asn-13 of LH-P is glycosylated (48). FSH-P suburnt [58857-12-8] is glycosylated at two sites, Asn-13 and 30. Based on interactions of synthetic peptides with the LH receptor, loops formed by P93—100 and P38—57 may be essential for hormone bioactivity (48). Highly conserved sequences between residues 31—37 have been implicated in the formation of the a—P suburnt dimer (48), which is absolutely necessary for the expression of bioactivity. 

The chemokine fold (Fig. 1C) consists of a flexible N-terminus, an N-loop, occasionally a 3io helix, an antiparallel three-stranded P-sheet, and a C-terminal a-hehx. Within the antiparallel three-stranded P-sheet, the pi-strand is connected to P2-strand by the 30s loop and p2-strand is
