EXPERIMENT NO. 15 PROTEIN CHARACTERIZATION BY ELECTROPHORESIS Abstract The molecular weights of protein extracts were assessed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Two sets of four protein samples‚ standard bovine serum albumin (BSA)‚ invertase‚ egg albumin‚ and casein‚ were prepared; one set containing β-mercaptoethanol (BME) while the other did not. These were then analyzed through SDS-PAGE with 12.5% resolving gel‚ prepared using 2 M Tris-HCl at pH 8

ABSTRACT The title of our project was Bilimbi fruit as an alternative stain remover. The purpose of this experiment was to find out if Bilimbi can remove stains from our clothes. We all know that teenagers today are very eligible especially in wearing dress. We conduct this kind of study to be able to have another background study about natural bleaching agent and to build natural product that is a solution for a stains The procedure involved was to apply the extract of Bilimbi to the clothes

significantly after which they can be seen under the light microscope as distinct thread-like structures. Chromosomes are usually studied by obtaining actively dividing tissue‚ fixing the material to kill the cells‚ and to preserve their structure‚ staining the chromosomes with a dye‚ and then observing them with a microscope. By studying mitosis in this way‚ changes that occur in the chromosomes can be observed and the visible events that bring about the process of heredity in somatic (body) cells

I allowed her to led the discussion on stains and she pointed out to coffee and smoking habit as potential reasons for the staining. Once she started talking about smoking‚ I asked her permission to collect some information on smoking history. I learned that she has been

Compound Microscope Parts A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially‚ a compound microscope consists of structural and optical components. However‚ within these two basic systems‚ there are some essential components that every microscopist should know and understand. These key microscope parts are illustrated

Solder (/ˈsoʊldə/‚[1] /ˈsɒldə/[1] or in USA /ˈsɒdər/[2]) is a fusible metal alloy used to join together metal workpieces and having a melting point below that of the workpiece(s). Soft solder is typically thought of when solder or soldering is mentioned‚ with a typical melting range of 90 to 450 °C (190 to 840 °F).[3] It is commonly used in electronics‚ plumbing‚ and assembly of sheet metal parts. Manual soldering uses a soldering iron or soldering gun.Alloys that melt between 180 and 190 °C (360
