What else can I help you with?
If iodine were not available how would you determine whether starch hydrolysis occurred?
You could use iodine in a starch hydrolysis test to detect the presence of starch. Without iodine, alternative methods such as using enzymatic assays to directly measure the breakdown products of starch hydrolysis could be employed. Additionally, techniques like TLC or HPLC could be used to analyze the carbohydrate composition before and after the hydrolysis process.
How long did the starch react with achromatic point?
Achromatic means "without color." During a hydrolysis test, starch auger is used to grow bacteria. An iodine reagent is used to flood the plate. The starch is dyed a blue-brown color. Areas where the starch has been completely digested by the bacteria, are clear. That is known as the achromatic point, or the point at which all the starch has been consumed and the iodine does not dye the auger.
Is DCPIP the same as iodine solution?
No, they are not the same. DCPIP (2,6-dichlorophenolindophenol) is a chemical dye commonly used as an indicator in redox titrations. Iodine solution is a solution containing iodine, often used in starch tests and iodometric titrations.
Can you use hair dye before radioactive iodine treatment?
It's generally recommended to avoid using hair dye before radioactive iodine treatment. Hair dye can contain certain chemicals that might interfere with the treatment or affect the thyroid's ability to absorb the radioactive iodine. It's best to consult your healthcare provider for specific guidance based on your individual situation.
A method of tagging antibodies with a fluorescent dye to detect or localize antigen-antibody combinations is known as?
Immunofluorescence staining. This technique involves binding a fluorescent dye to antibodies, which can then be used to detect and visualize specific antigens in a sample.
What is a Contrast agent made of?
It is usually a barium or iodine dye
What is a Contrast medium made of?
It is usually a barium or iodine dye
What radioactive material is used in Dye Tagging?
In dye tagging, the radioactive material typically used is a radioisotope of iodine, such as iodine-125 or iodine-131. These isotopes emit gamma radiation that can be detected using specialized equipment for tracking and monitoring purposes.
Why is Iodine used in Gram staining?
Iodine is used in Gram staining as a mordant, which helps to bind the crystal violet dye to the cell wall of bacteria. This mordant-iodine complex forms larger complexes with the crystal violet dye, making it difficult for the dye to be washed away during the decolorization step. This allows for differentiation of Gram-positive and Gram-negative bacteria based on their ability to retain the crystal violet dye.
How long do you have to dry tie dye when removed from the dye bath?
just set it out until you detect it is dry!
How is iodine used as a mordant?
As per the exact chemistry, I am unsure, but basically the iodine acts to "set in" the stain by reacting the dye (crystal violet) from the previous step with the peptidoglycan layer, forming a layer which is now insoluble in the following step where the layer is washed with EtOH. If the cell is Gram (-), the iodine doesn't do much and the dye is washed away.
What does the presence of blue color means in variegated leaf experiment of photosynthesis?
By blue color I assume you mean an added dye that shows how some parts of the leaf can photosynthesize and others not. The easiest of these experiments is to place the leaf in boiling ethanol (alcohol) and when drained of colour spread out on a flat surface. Soak the leaf in iodine and the green parts will turn blue/black and the non green parts will stay the yellowish brown colour of iodine. The green parts contain starch (a more compact form of glucose) which makes iodine turn blue/black. The blue/black is what will show starch is present.
