1. Colour Fastness to Light This method is intended for accessing the resistance of the colour of textiles to the action of daylight. Principle: A specimen of the textile is exposed to the light from a Xenon arc lamp under prescribed conditions‚ along with eight dyed wool standards. The fastness is assessed by compared the fading of the textile with that of the standards. Apparatus and Materials: - Blue standards - Humidity Test Control Fabric - Light fastness test apparatus containing

There were also three very large‚ odd shaped areas with distinct edges. Part 4: Direct Staining: Record your observations for each sample. Slide One: There were two distinct clusters that were easily noted. All the cells were cocci. Some of the cells were huge while others were practically nonexistent. Slide Two: There were layers of cells

contain cocci with direct staining. At direct staining plaque smear contain cocci and bacillus. Yeast with indirect staining contains cocci as well. On same picture bacteria are singled while on some pictures bacteria are in group and uneven clusters. Different type of stain plays role to differentiate the shape of bacteria. C: When we are talking about difference between direct and indirect stains‚ main importance is acidity of the dye. Dye that we are using in direct staining is basic. The colored

stained if the dyer solution is used at the specific pH at which the reactive groups are fully ionized. To achieve full ionization of the reactive groups‚ some alcian blue methods begin with a rinsing of sections in the appropriate pH solution prior to staining with the dye solution. In general‚ strongly sulfated mucins react more consistently at low pH levels. Above a pH of 1.0 their reactions are variable. At a pH of 0.2 only strongly sulfated mucosubstances will be demonstrated‚ while weak sulfated mucins

This technique was called staining‚ and was when one would stain nervous tissue before examining to under a microscope. However‚ several years later in 1873‚ Camillo Golgi came out with a new‚ improved staining method. The staining technique‚ allows the frequently transparent microbial cytoplasm’s to be seen with the light of the microscope by staining them. Through this new method there were several new discoveries‚ surrounding the nervous
