Endoscopic retrograde cholangiopancreatography (ERCP) uses a dye to highlight the bile ducts in your pancreas. During ERCP‚ an endoscope is passed down your throat‚ through your stomach and into the upper part of your small intestine. A dye is then injected into the pancreatic and bile ducts through a small hollow tube (catheter) that ’s passed through the

Important aqueous solutions used throughout the experiment were distilled water‚ Coomassie brilliant blue G-250 (CBBG) and BSA. The acidic CBBG dye was used to stabilize the binding of this to the BSA‚ therefore increasing the maximum absorption from 465nm to 595nm (Spector‚ T. 1978). The spectrophotometer is an absorbance measuring instrument that produces light through two bulbs; the first a

A Basic Understanding of Microscopy Assignment 1 Kaplan University-Microbiology Since microorganisms are not visible to the eye‚ the essential tool in microbiology is the microscope. One of the first to use a microscope to observe microorganisms was Robert Hooke‚ the English biologist who observed algae and fungi in the 1660s. In the 1670s‚ “Anton van Leeuwenhoek‚ a Dutch merchant‚ constructed a number of simple microscopes and observed details of numerous forms of protozoa‚ fungi‚ and bacteria”
