Stainin g What is Cellular Staining? Cell staining is a technique that can be used to better visualize cells and cell components under a microscope. By using different stains‚ one can preferentially stain certain cell components‚ such as a nucleus or a cell wall‚ or the entire cell. Most stains can be used on fixed‚ or non-living cells‚ while only some can be used on living cells; some stains can be used on either living is or non-living What Cellularcells. Staining? The most basic reason that cells

Abstract This experiment was carried out to perform staining methods on microbes‚ explain the mechanisms of staining‚ namely‚ simple staining‚ and learn how to use the microscope. The experiment setting was kept as sterile as possible when conducting the experiment. The microbes under the microscope were drawn out and labelled. In conclusion‚ different staining techniques are used to determine the presence of certain exterior structures of the bacteria like the cell envelope or just to identify

Micro Biology Lab Gram Staining Lab Report Purpose The purpose of this lab was to experiment with a staining technique called Gram Staining. Gram Stains is used to identify and classify bacteria‚ it is a differential stain that allows you to classify bacteria as either gram-positive or gram-negative. The foloowing is a breif summerary of the gram staining procedure. Apply the primary stain Apply Mordant Apply decolorizing agent Apply the secondary stain Bacteria that

GRAM STAINING EXPERIMENT CONDUCTED ON 9/29/2013 Introduction: The Gram stain is a useful stain for identifying and classifying bacteria. The Gram stain is a differential stain that allows you to classify bacteria as either gram positive or gram negative. This gram stain technique was discovered by Hans Christina Gram in 1884. The gram stain procedure separates all bacteria into one of two groups - into gram-negative bacteria which do not stain purple and into gram-positive

GRAM STAIN THEORY: The most widely used staining procedure in microbiology is the Gram stain‚ discovered by the Danish scientist and physician Hans Christian Joachim Gram in 1884. Gram staining is a differential staining technique that differentiates bacteria into two groups: gram-positives and gram-negatives. The procedure is based on the ability of microorganisms to retain color of the stains used during the gram

Identification of Unknown # 15 Abstract. One of the most fundamental differential staining techniques used in the study of bacteriology is gram staining. There are two main types of bacteria‚ gram negative and gram-positive. The purpose of this experiment was to perform a variety of tests to identify the bacteria contained in the unknown sample labeled number 15. The following are the tests that were used to identify the two different bacteria. The
