Penetration of zona-free hamster oocytes by human spermatozoa after preincubation with BWW medium (standard technique) or a buffer system containing egg yolk (TESTY) was compared by applying both treatments to aliquots of 60 ejaculates from 34 patients. The TESTY-treated spermatozoa

We examined the suitability of nine organic buffers for studying calcium binding to albumin by equilibrium dialysis. Results obtained with defatted human serum albumin showed that 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES) and 2-([tris(hydroxymethyl)methyl] amino)ethanesulfonic acid were superior. Scatchard analysis of the experimental

Several cryoprotective media currently in use for human sperm cryopreservation have been directly compared with each other by use of a static vapor freezing technique. The TEST-citrate-yolk buffers with glycerol resulted in the highest motility and longevity after thawing; thus

In homogenates of guinea-pig brain minus cerebellum, the delta-binding of 1.5 nM [3H]-[D-Pen2,D-Pen5]enkephalin is little affected by the type and concentration of the three buffers, Tris-HCl, HEPES-KOH, or TES-KOH (10-75 mM). However, the mu-binding of 1 nM [3H]-[D]Ala2,MePhe4,Gly-ol5]enkephalin or the

We used the Ussing short-circuit technique to investigate the role of HCO3- in the adenosine 3',5'-cyclic monophosphate (cAMP)-dependent secretory response of the human distal colon. In HCO3(-)-free 4-(2-hydroxyethyl)-1-piperazineethanesulphonic acid (HEPES)-Ringer's, forskolin (10 mumol l-1 mucosal and serosal) evoked a sustained
