What is the difference between iodine and grams iodine?

Next, a Gram’s iodine solution (iodine and potassium iodide) is added to form a complex between the crystal violet and iodine. This complex is a larger molecule than the original crystal violet stain and iodine and is insoluble in water. However, the decolorized Gram negative cells are stained red.

How much iodine is in a drop of lugol’s?

Calculating Number of MG’s of Iodine and Potassium Iodide per Drop of Lugol’s Solution: LUGOL’S 5%: Each VERTICAL drop is about 6.25 mg’s of iodine/potassium iodide (2.5 mg iodine, 3.75 mg potassium iodide) and 2 drops is about 12.50 mg’s of iodine/potassium iodide (5.0 mg iodine, 7.50 mg potassium iodide).

Is lugol’s iodine and Gram’s iodine the same?

Lugol’s iodine solution is used for Gram staining and can be used as an antiseptic and disinfectant for emergency disinfection of drinking water, and as a reagent for starch detection in routine laboratory and other medical tests.

What is gram iodine?

Gram’s iodine is used in Gram staining procedure to differentiate gram positive and gram negative organisms. Gram’s iodine acts as a mordant that causes the crystal violet to penetrate and adhere to the gram –positive organisms. Different mechanisms have been proposed to explain the gram reaction.

What is the purpose of gram iodine?

What happens if you don’t add iodine to a Gram stain?

During the gram staining process, the gram-positive bacteria appear violet because it has a thick peptidoglycan layer. The iodine acts as mordant and it does not use as a stain. It helps to fix the crystal violet inside the peptidoglycan layer. If iodine is not added, it would appear purple rather than pink.
