THE USE OF HYDROSOL HEXACIANFERRATE (II) FERRUM (III) FOR DEVELOPING DIAGNOSTIC LATERAL FLOW TESTS

Cover Page

Abstract


On the basis of synthesized negatively charged hydrosol hexacianferrate (II) ferrum (III) (HCFF) by diameter 10–20 нм are received stable conjugates with antibodies and antigens glycoprotein and lipopolysaccharide (LPS) nature. Synthesized hydrosol (HCFF) is new type of a disperse phase in the lateral flow assay. Conjugates mentioned above were applied for construction lateral flow tests-systems for revealing cholera toxin, the rabbit antibodies to recombinant glycoproteine complex from Micobaсterium tuberculosis H37 Rv, human immunoglobulin, LPS antigens S. typhimurium, S. enteritidis. Developed lateral flow tests-systems had high analysis speed (5–7 min), good specificity and sensitivity: on cholera toxin of 2,0 ug / ml, on LPS antigens S. typhimurium, S. enteritidis 0,5 ug / ml.
