FIELD: medicine, pharmaceutics. n SUBSTANCE: invention refers to medicine. What is presented is an antibody produced of hybridoma ATCC No. PTA-7580 specific to human protein tyrosine phosphatase beta (HPTPβ). What is described is a Fab version of said antibody, as well as versions of method of treating and pharmaceutical compositions based on the use of the antibodies. Binding the antibody and HPTPβ intensifies Tie-2 signal transmission, and thereby increases angiogenesis, whereas binding the Fab antigen-binding antibody fragment and HPTPβ inhibits Tie-2 signal transmission, and thereby reduces angiogenesis. n EFFECT: use of the invention can find application in medicine for treating the diseases related to disturbed angiogenesis. n 21 cl, 12 dwg, 1 tbl, 5 ex |
