and what if any safety precautions needed to be followed. For this lab I had to prick my finger‚ then with the bleach solution I had to dab it and then carefully drop the blood on the slide. Once I was finished I had to take the second slide and smear the blood. I had to let the slide dry. Then I had to prick my finger again and make 3 more slides. Then I had to mix the chemical with a toothpick and then look under with the microscope. Because I had to prick my finger I had to make sure the pin

Some cancer prevention is based on systematic screening in order to detect small irregularities or tumors as early as possible even if there are no clear symptoms present. Breast self-examination‚ mammograms‚ testicular self-examination‚ and Pap smears are common screening methods for various cancers. Researchers from Northwestern University Feinberg School of Medicine in Chicago reported in the journal Circulation that the 7 steps recommended for protection against heart disease can also reduce

1 Biology 2070H - Lab #1 MICROSCOPY AND CHARACTERIZATION OF CELLS Introduction: Cells can be very difficult entities to study. They are usually very small and transparent‚ yet extremely complex. Fortunately‚ there are many tools available to the cell biologist that aid in their study. The light microscope is to this day perhaps the single most important instrument used in Cell Biology. It is used under bright field conditions to study the organization of cells in fixed and stained sections

distinguishing between types of bacteria and it is the most useful staining procedure used today (Seeley and others 1991). In this kind of staining procedure‚ a basic dye‚ a mordant‚ a decolorizing agent and a counterstain is needed. First‚ prepare smears of an unknown culture‚ then spread a drop of the culture on a slide and let it air dry. After air drying‚ heat fix this slide by passing the slide three times through a bunsen flame. This allows the cells to adhere to the slide. Following the heat

will be added to the slide. A smear will be prepared on this droplet by using fresh culture of bacteria and then will be air dried and heat fixed. The smear will be flooded with malachite green (0.5% aqueous solution). The slide will be heated so that malachite green will be steamed for 5 min but will not allow evaporating. More malachite will be added by heating the slide over again. Then the slide will be cooled and will be washed under running water. Then‚ the smear will be flooded with counter
