Rat Thoracic Aorta Myoblast Cell Actin

YFP Bandpass Emission (Narrow Bandwidth Excitation) Blue-Green Set

Fluorescence emission intensity from a culture of embryonic rat thoracic aorta medial layer (A-10 line) myoblast cells that were transfected with a pEYFP-Actin plasmid subcellular localization vector. Cells were transiently transfected and cultured in nutrient medium for a minimum of 24 hours before recording images. The enhanced yellow fluorescent protein gene used in these studies contains several important amino acid substitutions that shift the emission maximum of green fluorescent protein (GFP) by approximately 18 nanometers, from 509 to 527 nanometers. However, the fluorescence emission still appears green when observed in the microscope eyepieces. Note the complex network of actin filaments and stress fibers that extend throughout the cytoplasm and inhabit the cortex in this cell line.
