Yuri Anthony D. Sucgang BMLS-IA Electrophoresis Machine Gel Electrophoresis Apparatus(Aragose Gel) Electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. Gel electrophoresis is a laboratory procedure used to separate biological molecules with an electrical current. In this lesson‚ we’ll review how agarose gel electrophoresis works and introduce the equipment necessary to perform an electrophoresis experiment.

Most water pollutants are eventually carried by rivers into the oceans. In some areas of the world the influence can be traced hundred miles from the mouth by studies using hydrology transport models. Advanced computer models such as SWMM or the DSSAM Model have been used in many locations worldwide to examine the fate of pollutants in aquatic systems. Indicator filter feeding species such as copepods have also been used to study pollutant fates in the New York Bight‚ for example. The highest toxin

2.1 Sanitation Methods There are Four Methods that conducted on the laboratories in order to detect the presence of microorganisms. There are Rodac Method‚ Swab Method‚ Rinse Method‚ and lastly Open Dish Method and it will be discussed in detail below. 2.1.1 Rodac Method The purpose of this Standard Operating Procedure is to describe a program that will adequately measure the efficacy of disinfection of Rooms and equipment in each laboratory‚ RODAC plates can detect the presence or absence of

in vegetable oil‚ the water breaks easily than the albumin and it didn’t mix with the oil. When albumin was added into the vegetable oil‚ a bubble forms because air is introduced into the system. The bubble formed remained stable due to protein adsorption at the bubble surface. Water bubble on the other hand breaks easily because it is less viscous than albumin. The second part is the determination of osmotic effect in frog’s blood‚ mammalian blood and plant. The frog and mammalian bloods are subjected

CHEMISTRY ISU: REFINEMENT OF CRUDE OIL My ISU will focus on Petroleum‚ a complex mixture of hydrocarbons that occurs in the Earth in liquid‚ gaseous‚ or solid forms. The term is usually restricted to the liquid form‚ commonly called crude oil‚ but as a technical term it also includes natural gas and the viscous or solid form known as bitumen. In its liquid and gaseous states‚ it is also known as Oil‚ or Crude Oil. Italicized are segments from my ISU or introductions to the planned topics.

In the end of the experiment the chromatoplate should show the polarity of the spots based on the adsorption of the spots in the mobile phase of the two-dimensional thin layer chromatography. Proper handling of the chromatoplate and developing chamber is recommended to avoid errors in the result. INTRODUCTION Lipids are substances found in living

Thin‑layer chromatography involves the same principles as column chromatography‚ it also is a form of solid‑liquid adsorption chromatography. In this case‚ however‚ in a plate of glass or rigid plastic‚ the solid adsorbent is spread as a thin layer (approximately 250 um). At the edge of the plate‚ 2-3 drops of solution was spotted at the origin‚ and the plate is placed
