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 is the importance of iodine after primary stain?
Iodine is used after the primary stain in the Gram stain procedure to form a complex with the crystal violet dye, which helps to stabilize the dye within the bacterial cell wall. This step enhances the retention of the primary stain in Gram-positive bacteria.
What are 3 uses of Iodine element?
Iodine is used in medicine as a sterilizing agent, and to help remove harmful levels of radiation from a patient. Iodine is also used, in small amounts, as a food additive to promote health Iodine is used as a dye though this use is less common today then it was in the past.
What is crystal violet iodine complex?
Crystal violet iodine complex is a chemical compound formed when crystal violet dye interacts with iodine. This complex is commonly used in microbiology as a stain for bacterial cells, allowing them to be visualized under a microscope. The crystal violet iodine complex binds to the peptidoglycan layer of bacterial cell walls, imparting a purple color to the cells.
Function of iodine in Gram stain?
iodine act as a mordant..on the gram positive bacteria which got really thick and abundence of peptidoglycan layer, the crystal violet will fix to the peptidoglycan layer..meanwhile in gram negative bacteria which is lack of peptidoglycan layer, the alcohol or acetone will wash it away
Side effects from ct scan dye inflitration?
if you're allergic to iodine, you'll probably have an allergic reaction
Is it safe to use isovue if you are allergic to shellfish?
Isovue should not be used if a person is allergic to shellfish or iodine. Isovue is usually administered by vein and is a dye used in x-raying.
If you are allergic to hair dye will you be allergic to highlights?
Yes.
What is the chemical name of the drug Pyridium?
Pyridium is the North American brand name of phenazopyridine, a drug used to treat urinary tract infections. It is a type of azo dye and as a result stains the urine a distinctive dark orange color when taken internally.
If I am allergic to eyebrow tint am i allergic to hair dye?
Probably
Can someone with a shellfish allergy have a thyroid scan?
The reason why shellfish allergy is asked is because of the link between shellfish allergy and iodine allergy (shellfish are rich in iodine). That does not mean that if your allergic to shellfish then you are allergic to iodine - you may be allergic to another component that is in the shellfish. Iodine is used in the thyroid scan as a dye and is injected into your veins. If you are allergic then the reaction would be quite quick and potentially serious. Asking about a shellfish allergy is to try to risk stratify those that may be more susceptible for a reaction and "prepare" the technician / radiologist for the worse case scenario. The main allergic reaction we would be worried about would be true anaphylaxis (if you've not heard of this then you probably not had it). Rashes and facial swelling would indicate a allergic reaction. Sickness, diarrhea and feeling "off" would suggest an intolerance rather than a true allergic reaction. Happy New Year! El Tango
What is Zak Bagans allergic to?

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.
