Polyacrylamide gel electrophoresis (PAGE) is a technique widely used in biochemistry, forensic chemistry, genetics, molecular biology and biotechnology to separate biological macromolecules, usually proteins or nucleic acids, according to their electrophoretic mobility. Electrophoretic mobility is a function of the length, conformation, and charge of the molecule. Polyacrylamide gel electrophoresis is a powerful tool used to analyze RNA samples. When polyacrylamide gel is denatured after electrophoresis, it provides information on the sample composition of the RNA species.Hydration of acrylonitrile results in formation of acrylamide molecules (C3H5NO) by nitrile hydratase. Acrylamide monomer is in a powder state before addition of water. Acrylamide is toxic to the human nervous system, therefore all safety measures must be followed when working with it. Acrylamide is soluble in water and upon addition of free-radical initiators it polymerizes resulting in formation of polyacrylamide. It is useful to make polyacrylamide gel via acrylamide hydration because pore size can be regulated. Increased concentrations of acrylamide result in decreased pore size after polymerization. Polyacrylamide gel with small pores helps to examine smaller molecules better since the small molecules can enter the pores and travel through the gel while large molecules get trapped at the pore openings.
As with all forms of gel electrophoresis, molecules may be run in their native state, preserving the molecules' higher-order structure. This method is called native-PAGE. Alternatively, a chemical denaturant may be added to remove this structure and turn the molecule into an unstructured molecule whose mobility depends only on its length (because the protein-SDS complexes all have a similar mass-to-charge ratio). This procedure is called SDS-PAGE. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) is a method of separating molecules based on the difference of their molecular weight. At the pH at which gel electrophoresis is carried out the SDS molecules are negatively charged and bind to proteins in a set ratio, approximately one molecule of SDS for every 2 amino acids.: 164–79 In this way, the detergent provides all proteins with a uniform charge-to-mass ratio. By binding to the proteins the detergent destroys their secondary, tertiary and/or quaternary structure denaturing them and turning them into negatively charged linear polypeptide chains. When subjected to an electric field in PAGE, the negatively charged polypeptide chains travel toward the anode with different mobility. Their mobility, or the distance traveled by molecules, is inversely proportional to the logarithm of their molecular weight. By comparing the relative ratio of the distance traveled by each protein to the length of the gel (Rf) one can make conclusions about the relative molecular weight of the proteins, where the length of the gel is determined by the distance traveled by a small molecule like a tracking dye.For nucleic acids, urea is the most commonly used denaturant. For proteins, sodium dodecyl sulfate (SDS) is an anionic detergent applied to protein samples to coat proteins in order to impart two negative charges (from every SDS molecule) to every two amino acids of the denatured protein.: 161–3 2-Mercaptoethanol may also be used to disrupt the disulfide bonds found between the protein complexes, which helps further denature the protein. In most proteins, the binding of SDS to the polypeptide chains impart an even distribution of charge per unit mass, thereby resulting in a fractionation by approximate size during electrophoresis. Proteins that have a greater hydrophobic content – for instance, many membrane proteins, and those that interact with surfactants in their native environment – are intrinsically harder to treat accurately using this method, due to the greater variability in the ratio of bound SDS. Procedurally, using both Native and SDS-PAGE together can be used to purify and to separate the various subunits of the protein. Native-PAGE keeps the oligomeric form intact and will show a band on the gel that is representative of the level of activity. SDS-PAGE will denature and separate the oligomeric form into its monomers, showing bands that are representative of their molecular weights. These bands can be used to identify and assess the purity of the protein.: 161–3
Mga boss baka may kayang tumulong sa akin. May nang hahäçk ng page ko sa facebook. Tuwing tinatangal ko siya sa Page role bumabalik siya after 24hrs. hindi ko naman siya ma search kasi iba yung isang letter ng name niya. Patulong naman po, eto po screenshot sa Facebook. Thank you po
matanong lods paano matagal o ma log out yung facebook page na tinatrabahoan
ko dati na ni link sa facebook account ko paligi akong na notify kapag my message to post sa facebook page?
Help po after button click po Page Personnel Button mag play ng audio chime.mp3 sa folder

Just bored sa workplace kaya i decided to look back in time kung ang PHCorner existed in early 2000s. (or late 90s.)
Typical "Page could not be loaded error".
What it would looked like if that error page is from the late 90s?
Yep. That's a very old OG internet explorer 6! On a very old OG...
Good PM Maam/Sir,
Looking po sino po may kaya mag down nang facebook page nang isang scammer. Willing to pay. Yung legit po sana. Thanks po.
Details: Ginaya nya po yung facebook page namin at dun siya nag sscam gamit ang business name po namin.

may narestricted naba dito by using autolikes? may isa akong page medyo may pagka sê×ÿ yung content, okay naman ung page quality nya, pero may naflag na mga post and naging NOT Recommendable ung page
batas ni fb is hindi na ibabalik ung recommended basta may history na
so may business page...

ano kaya may problema dito mga paps? nakan desktop naman ako.
Hello . Magandang hapon mga ka PHC.
Need ko po ng tulong about sa deletion ng FB page ko .
Need ko Kasi maidelete ang page ko kaso Wala nakong access parang binanned ni FB . Pero na sesearch pa sya.
Pano kaya madelete un kung Wala ng access ?
selling my fb page 5k plus organic followers wlang boosting boosting sa page ko.organic lahat ng followers ko taz almost 4m reach.. ma create ko to november 22 pm sa enterested
Patulong mga boss kada log in ko kasi sa pldt namin kailangan daw palitan yung password pero kahit na palitan na palagi parin nag required na palitan ulit password ng wifi paano ba ito i skip?
