Lamellar pigment based on iron(III) oxide

Lamellar pigment based on iron(III) oxide. Raspopov, Yu. G.; Lenev, L. M.; Kalinichenko, I. I.; Sevost'yanova, O. V.; Nosach, V. F. (USSR ). U.S.S.R. SU 1089097 A1 30 Apr 1984 From: Otkrytiya, Izobret., Prom. Obraztsy, Tovarnye Znaki 1984, (16), 77. (Russian). (Union of Soviet Socialist Republics). CODEN: URXXAF. CLASS: IC: C09C001-24. APPLICATION: SU 82-3512971 19 Aug 1982. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 49 A lamellar pigment is manufd. by mixing an Fe compd. with NaCl and KCl, heat-treating the mixt., leaching the product, filtering, and drying. The app. is simplified and the energy consumption reduced by using Fe2(SO4)3 in a mixt. with NH4Cl or FeNH4 alum [10138-04-2] as the Fe compd. After mixing with the chlorides, melting was performed, and then the compn. was heated at 800-900° until complete dissocn. was attained.

Observations on the use of isoelectric focusing for subtyping in the transferrin (Tf) system

Observations on the use of isoelectric focusing for subtyping in the transferrin (Tf) system. Rand, Steven; Kofahl, Anke; Brinkmann, Bernd (Inst. Rechtsmed., Muenster, Fed. Rep. Ger.). Adv.Several reagents with their cas registry numbers 10138-04-2 and 10045-89-3 are used here. Forensic Haemogenet., 1, 111-15 (English) 1986. CODEN: AFHAE8. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Section cross-reference(s): 9 Ammonium ferrous sulfate, ammonium ferric sulfate, and 2-mercaptoethanol [60-24-2] were compared for use in pretreatment of human blood serums for transferrin subtyping by polyacrylamide gel isoelec. focusing. Pretreatment with Fe2+ and Fe3+ salts produced clear results in both cases, but the bands were always more intense after using the Fe2+ salt. The band patterns were also different. Pretreatment with mercaptoethanol did not improve the band resoln. Thus, although transferrin subtyping was possible and in most cases the correct phenotype identified, errors could be made in interpretation. Until this is resolved, it would be better to use the title system cautiously in casework. .
