Background: Lipid and protein composition varies in tissue types. Results: When comparing liver‚ muscle‚ and adipose tissue‚ adipose tissue had the highest percent lipid and liver tissue had the highest percent protein. Conclusion: Based on analysis of the gels‚ the liver appeared to have the most variety in proteins when comparing liver‚ muscle‚ and adipose tissue. Significance: In order to determine the composition of a tissue‚ specific macromolecules can be extracted‚ quantified‚ and analyzed

surface stains‚ where the staining substance is spilled out onto the surface or material and is trapped in the fibers‚ pores‚ indentations or other capillary structure of that surface. The material that is trapped coats the underlying material‚ and the stain reflects back light according to it’s own color. Applying paint‚ spilled food‚ and wood stains are of this nature. A secondary method of stain involves a chemical or molecular reaction between the material and the staining material. Many types

I am writing this letter to give my highest possible recommendation for Ms. Adebimpe Adelaja. I am Professor and Vice Chair for Strategic Technologies in the Department of Pathology and Laboratory Medicine‚ UC Davis. I had the opportunity to get to know Adebimpe when I served as a mentor for the Hugh Edmonson Summer Internship. On the first day of the internship‚ I was able to have a discussion with each student and select the student I would work with for the next 8 weeks. Adebimpe distinguished

distinct edges. Part 4: Direct Staining: Slide One: There were two clusters that were fairly easy to recognize. All of the cells were cocci. Some of the cells were large while others were practically nonexistent. Slide Two: There were different layers of cells. The cells were rectangular in shape and varied in size. A nucleus was visible in each cell. Slide Three: This slide was a mixture of different shapes. Nothing was recognizable. Part 5: Indirect Staining: Chains of both cocci and

Lab 4 – The Cell Answer Key Procedure 4.3 Draw a picture of a single Elodea cell and label all visible structures. See the diagram in your lab manual. Without staining‚ the only structures that should have been clearly visible should have been the cell walls and the green chloroplasts. Is this cell prokaryotic or eukaryotic? ______Eukaryotic_______________________ What evidence do you have to support this claim? The presence of organelles (chloroplasts) and its large size.

"TURMERIC: HOMEMADE WHITENING TOOTHPASTE" CHAPTER I Abstract: We are only recently becoming more aware of all the benefits of turmeric to our bodies. In addition to health benefits‚ turmeric also seems to have beauty benefits. Not only is it great for the skin‚ it also seems to whiten teeth! It is very skeptical‚ but the root plant we once thought to be only dyes to textiles can somewhat really make the teeth whiter and brighter! It sounds a little counter-intuitive to apply a rich yellow substance

important key in understanding plant biology‚ aiding this study are the fundamentals of histology and techniques in histochemistry. This experiment involved exercising free-hand sectioning techniques‚ learning maceration procedures and application of staining techniques. Sudan dye for Lipids and IKI test for starch were applied on section stem‚ root and leaf parts of Tridax procumbens. Stem cross-section of T. procumbens showed distinct ground tissues and fourteen to sixteen vascular bundles organized

The last structure of the osteon that can be seen in this figure is the cement line. This is a thin line that surrounds the entire osteon. It is purple in colour which shows the haemotoxylin dye of H&E is staining the cement line. This is turn means that this part of the osteon is a basophilic
