Здравствуйте. Перевожу учебник в качестве домашнего задания. Встречаются конструкции типа
from the low- to high-500 nm
Что это означает? от нижних до верхних значений пятисот? Не подскажете, как это будет по-русски?
Употребление в тексте: Rhodamine derivatives have effective excitation wavelengths within the visible light spectrum in the approximate range
from the low- to high-500 nm, depending on the particular derivative.
читать дальшеTheir associated emission wavelengths occur from the mid- to high-500 nm—with Texas Red derivatives typically over 600 nm—within the orangetored visible spectrum. The quantum yield of rhodamine derivatives is generally less than that of fluorescein—only about 25%. However, its fluorescent intensity fades more slowly than fluorescein when it is dissolved in buffers, exposed to light, or stored for extended periods. In addition, its orange-to-red luminescence is in stark contrast to the green of fluorescein, thus these two types of probes form an ideal pair for use in double staining techniques, especially in fluorescent microscopy.
