Accumulation of free amino acids in growing Xenopus laevis oocytes.

abstract：:Epi 1, a monoclonal antibody, was generated against an epidermal specific epithelial antigen; it does not stain neural epithelium. We have used Epi 1 as a marker to determine when the spatial patterns delineating neural from nonneural epithelium become established. We used ventral ectoderm in a sandwich assay to show ...

abstract：:Calcium influx is known to be prerequisite for membrane fusion of myoblasts. However, little is known about the channels that are responsible for the entry of calcium into the cells. Here we show that K(Ca) channels and stretch-activated channels are involved in the calcium influx. Upon analysis of single-channel reco...
