摘要

FIELD: biotechnology, immunology. SUBSTANCE: composition has the following quantitative ratio of components, wt.-%: bovine serum albumin 0.5-1.5; ethylenediaminetetraacetate 0.01-0.1; ascorbic acid 0.01-0.001; peptone 0.5-2.5; sucrose 4.5-10.0; potassium chloride 0.5-1.5; bacteriostatic 0.01-0.15 and negative donor serum of the group 0(1) - the rest up to 100%. Stabilizing composition provides the retention of specific indices of IgM-antibodies in reference-sera for the long time (for two years, not less) at their storage at (+4 <EMI ID=0.363 HE=3 WI=3 TI=CHI> 2 C). EFFECT: improved quality and properties of the composition. 2 cl, 2 tbl, 3 ex
