Indium - Wikipedia

Indium is a chemical element with the symbol In and atomic number 49. Indium is the softest metal that is not an alkali metal.It is a silvery-white metal that resembles tin in appearance. It is a post-transition metal that makes up 0.21 parts per million of the Earth's crust. Indium has a melting point higher than sodium and gallium, but lower than lithium and tin.

Indium 113m - an overview | ScienceDirect Topics

Indium is a metal that can be used as an iron analog; it is similar to gallium. Isotopes of interest are 111 In and 113m In. Indium-111 has a physical half-life of 67 hours and is produced by a cyclotron. The principal photons are 173 keV (89%) and 247 keV (94%). Indium-113m can be conveniently produced by using a 113 Sn generator system.

Indium-113m Diethylenetriaminepentaacetic Acid (DTPA): A ...

Materials and Methods. 113m In-DTPA complex was prepared as suggested by Stern et al. (2). Twenty millicuries of 113m In was eluted with 0.05 N HCl (about 8 ml initially) from a tin-113 generator. Two hundred μg of carrier iron (0.2 ml FeCl 3 in 0.1 N HCl) was added and the solution well stirred. After this, 1.6 mg of DTPA (in 1.0 ml pyrogen-free water) was added, and the mixture was then ...

113m In-DTPA, a useful compound for the determination of ...

For measurement of glomerular filtration rate the usefulness of diethyl triamino penta acic (DTPA) labelled with 113m Indium has been explored.. The labelling procedure is very simple, since eluate from an 113m In generator can be used directly for labelling DTPA.. The in vitro and in vivo binding of 113m In to DTPA in competition with serum proteins was studied by gel-filtration.

Mar 01, 1995· Indium-113m-DTPA was the tracer used in our study to determine the liquid gastric emptying rate in dual-isotope solid-liquid emptying studies, however, cessation of the {sup 113}Sn/{sup 113m}In generator production makes it unavailable. Thus, development of alternative tracers to {sup 111}In-DTPA and {sup 113m}In-DTPA was essential.
