However, some sources recommend alternative dosing regimens. Food and Drug Administration-approved dosing of potassium iodide for this purpose with iobenguane, is as follows (per 24 hours): infants less than 1 month old, 16 mg children 1 month to 3 years, 32 mg children 3 years to 18 years, 65 mg adults 130 mg. However, since they may be ultimately metabolized or break down to radioactive iodide, it is common to administer non-radioactive potassium iodide to ensure that iodide from these radiopharmaceuticals is not sequestered by the normal affinity of the thyroid for iodide. These compounds contain iodine, but not in the iodide form. Thyroid iodine uptake blockade with potassium iodide is used in nuclear medicine scintigraphy and therapy with some radioiodinated compounds that are not targeted to the thyroid, such as iobenguane ( MIBG), which is used to image or treat neural tissue tumors, or iodinated fibrinogen, which is used in fibrinogen scans to investigate clotting. Radioactivity is also seen in the bladder. However, note unwanted uptake of radioiodine from the pharmaceutical by the thyroid gland in the neck, in both images (front and back) of the same patient. Image is by MIBG scintigraphy with radiation from radioiodine in the MIBG. Pheochromocytoma seen as dark sphere in center of the body. Dextrose or sodium thiosulfate are often added to iodized table salt to stabilize potassium iodide thus reducing loss of the volatile chemical. Potassium iod ate ( K I O 3) is used to iodize some salts so that the iodine is not lost by oxidation. The alkali metal iodide salt, over time and exposure to excess oxygen and carbon dioxide, slowly oxidizes to metal carbonate and elemental iodine, which then evaporates. The oxidation of iodide causes slow loss of iodine content from iodised salts that are exposed to excess air. For the latter, it is the most common additive used to "iodize" table salt (a public health measure to prevent iodine deficiency in populations that get little seafood). Potassium iodide is used as a nutritional supplement in animal feeds and also in the human diet. Potassium iodide is also used for the iodization of salt. Potassium iodide is available as a generic medication and over the counter. It is on the World Health Organization's List of Essential Medicines. Potassium iodide has been used medically since at least 1820. Commercially it is made by mixing potassium hydroxide with iodine. Potassium iodide has the chemical formula K I. While use during pregnancy may harm the baby, its use is still recommended in radiation emergencies. Other side effects include allergic reactions, headache, goitre, and depression. Ĭommon side effects include vomiting, diarrhea, abdominal pain, rash, and swelling of the salivary glands. As a supplement it is used in those who have low intake of iodine in the diet.

In the third world it is also used to treat skin sporotrichosis and phycomycosis.

As a medication it is used to treat hyperthyroidism, in radiation emergencies, and to protect the thyroid gland when certain types of radiopharmaceuticals are used. If you run out of DNA, do the same procedure all over again, don't think that your BAC sequence will be the same.Potassium iodide is a chemical compound, medication, and dietary supplement. So, culture a colony, make a mega prep, fingerprint it extensively to make sure that there is no rearrangement and that you are getting all bands right (you may have to do a southern, not just digest), and then use that same DNA for all your expts. This is generally not a big problem, but if your particular BAC has a lot of rearrangment prone sequence, you may get subtle or dramatic changes in restriction pattern. Not from many different colonies, nor from a colony that has been propagated many times over in between DNA preps. Whichever method you use, make sure that in all digest comparsions you are making, you have used a BAC DNA that have all come from a single colony on a plate.

I run gel and read nanodrop to identify the BAC quality and quantity then only digest it. I always use the QIAGEN Large Constrcut Kit to extract the BAC DNA. I hope you are using the same BAC preparation everytime.
