What is the point of mashing straberrys for DNA extraction?
Use the usual extraction protocol for plants: grind, liquid-liquid extraction, salting out.
What is precipitation of alumina?
Precipitation of alumina refers to the process of separating alumina (aluminum oxide) from a solution by causing it to form a solid or a gel. This is commonly done through the addition of specific reagents that cause the alumina to precipitate out of the solution, allowing for its separation and further processing.
Why do you use carrier RNA in extractions?
Carrier RNA is used in extractions to increase RNA yield, stability, and recovery. It helps to maximize the precipitation of RNA while reducing its degradation or loss during the extraction process. Carrier RNA also aids in the efficient isolation and purification of the target RNA by acting as a co-precipitant and increasing the effectiveness of RNA isolation reagents.
When mixing reagents always read the label?
Always read the label on reagents before mixing them to ensure that you are using the correct substances and following the proper handling instructions. Failure to do so can result in chemical reactions or hazards that could be harmful to your health or the environment.
Electrophilic and Nucleophilic Reagents?
ELECTROFILIC REAGENTS:It is the combination of two words(electro means electron and phile means loving).Therefore those reagents that contain positive charge on it are called eletrophilic reagents. These reagents have the property of attacking on the negative part of the other substance.Some of the reagents are(NO2+ ,SO3+) NUCLEOPHILIC REAGENTS:Combination(nucleo means nucleus and phuile means loving)
What are the best practices for using DNA extraction kits in a laboratory setting?
The best practices for using DNA extraction kits in a laboratory setting include following the manufacturer's instructions carefully, maintaining a clean work area to prevent contamination, using proper safety equipment such as gloves and goggles, and storing reagents at the correct temperature. It is also important to keep track of samples and reagents to avoid mix-ups and ensure accurate results.
What is the function of a wide mouth bottle?
This bottle is used to contain reagents.
Why saturated KCL in DNA extraction is used?
Saturated KCl precipitation is often used in DNA extraction for molluscan taxa. Molluscs produce a polysaccharide rich mucus that interferes with the reagents involved in DNA extraction. The KCl saturated solution is used right after the digestion step: about 1/4th of the volume of the digestion solution is added to the sample. Samples are then centrifugated at 14rpm for 15 minutes. The pellet formed will contain the polysaccharides and non digested tissue. The supernatant is extracted from the tube and used in the next steps of the DNA extraction.

What reagents break a double bond?
Reagents that break a double bond include hydrogenation reagents (such as H2/Pd or H2/Ni), halogenation reagents (such as Br2 or Cl2), and ozonolysis reagents (such as O3/Zn, and H2O). These reagents can break the double bond by either adding atoms across it or cleaving it into two separate fragments.
What do you mean by reagents in chemistry?
Chemical compounds used in laboratory are frequently called reagents.
What does extraction buffer do?
The most likely function of the extraction buffer would be to maintain an isotonic environment that favors the stability of the protein. An isotonic solution mimics the ionic environment if the cell and therefore would keep the protein in a stable form during the process of extraction. Proteins undergo changes in different ionic environments (different pH's) and it is essential to keep them in a stable form.
In what proportion do the reagents be added to make 1 liter solution of silver nitrate?
depends what reagents you are using. Look at the balanced chemical equation, the numbers in front of the reagents show you their respective proportions
Difference between precipitation titration and complexometric titration?
In precipitation titration, the formation of a solid precipitate is used to determine the endpoint of the titration, while in complexometric titration, a complex formation reaction is used to determine the endpoint. Precipitation titration is often used for specific ion determinations, while complexometric titration is used for determining metal ions by forming stable complexes with titrant.
