Measuring plant protein with the Bradford assay : 1. Evaluation and standard method.

abstract：:Mammalian scent marking is often associated with territorial defense. However, males and females may demonstrate different activity patterns and play different roles. Female mammals nurture the young during lactation, while males purportedly perform other tasks more frequently, such as territorial maintenance and defe...
