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...

Bacterial Smear Preparation and Simple Staining

techniques. Here they are; Simple staining: Only one type of dye used for simple staining and it stains all cells the same color. Creating contrast between cell and background to observe cell morphology is aimed. Differential staining: A differential stain uses more than one dye and stains different kinds of organism with different colors. Positive staining: If cell itself is stained it is called positive staining. It sticks with specimen and gives its color. Negative staining: If background is stained...

Gram Staining

 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 Staining

 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...

Lab Report #1 Microscopy and Staining

Microscopy and Staining Abstract The primary focus of this lab was on microscopy and simple stains. Microscopy that was used were magnification, slide preparation, and staining. Methylene blue, a simple staining component, was used to stain the slide in order to see the different microbes and determine their cellular shape. Introduction The purpose of this lab was to become familiar with the light microscope and how to accurately use it to view specimens. The staining method was used...

Theory of Staining Techniques

Theories of Staining Techniques Staining bacteria with different dyes via staining techniques, allows in distinguishing the microorganism from its backgrounds. Also, helps in studying different internal structures such as vacuoles, cell walls and spores in details (Seeley and others 1991). Some staining techniques such as Gram staining, endospore stain and capsule stain are some of the theories of stains used in bacteriology today. Also, these staining procedures help in determining properties...

Differential staining

MBK – Lab Report Differential Staining Questions: A. What is a differential stain? How is it different from a simple stain? 1. A differential stain is a stain that differentiates between gram-positive and gram-negative bacteria. Bacteria that stain purple are considered gram-positive and those that stain pink are considered gram-negative. 2. A simple stain is a stain that reacts with all microbes in and identical fashion. They are used to increase contrast. 3. They...

Gram Staining Lab Report

Introduction Gram staining was developed by Christian Gram in the 1800’s, a Danish bacteriologist. (Smith and Hussey, 2005) It was the first differential staining technique and most common used in microbiology. Furthermore, bacteria are transparent and cannot be seen through the microscope. For that reason, Gram staining is an important tool for distinguishing between two main types of bacteria Gram-positive and Gram-negative. The Gram stain differentiates the Gram positive and gram-negative on...
