FITC (389 g/mol) was one of the first dyes which was used for fluorescence microscopy and served as an origin for further fluorescent dyes like Alexa FluorÂ®488. Its fluorescence activity is due to its large conjugated aromatic electron system, which is excited by light in the blue spectrum.
Body odor is not catching. If the body odor is due to an infection, the infection may be contagious, such as a sexually transmitted disease. Inherited conditions may be passed on to children through the genes.ody odor is the term used for any unpleasant smell associated with a person's body. People usually associate body odor with sweat, but sweat by itself does not give off an odor.
Body odor (or B.O., bromhidrosis, osmidrosis or ozochrotia) is a perceived unpleasant smell our bodies can give off when bacteria that live on the skin break down sweat into acids - some say it is the smell of bacteria growing on the body, but it really is the result of bacteria breaking down protein into certain acids.
