... organ are potentially damaging to sperm, and large ejaculates may be better able to buffer against female spermicide and hence survive longer. Certainly the uterus of a female Drosophila is a ... ‘driving’ sperm was preferentially discarded by females. The authors confirmed that this effect was not simply due to a higher death rate of SR sperm in storage by assaying sperm morta...

Remarkably, we have found that, at least in some circumstances, a quanti- tative correlation to biophysical data can be obtained from a statistical analysis of selected phage populations ... the association of the variable heavy chain (V H )with protein A was used as a surrogate for direct stability measurements. The V H domains in camelid heavy chain antibodies are mos...
