Do patients with the heparin-induced thrombocytopenia syndrome have heparin-specific antibodies? John G. Adams, MD, Loren J.

Fig. 1 Demonstration of 50kd bands produced in SDS-PAGE by IgG+ plasmas 1 through 7 after immunoprecipitation after heparin exposure. IgG+ 6 did not stain as heavily as other plasmas, but 50 kd band can be identified. Identity of bands was confirmed by fluorescent-labeled anti-IgG reagents. (STD represents purified standard proteins (14.4 kd to 97.4 kd), BIO-RAD; 1-7 represent IgG+ plasmas 1 through 7).

Fig. 2 Example of 25 kd band (black arrow represents F(ab′)2 fragments) produced in SDS-PAGE after immunoprecipitation after heparin exposure of isolated F(ab′)2 fragments of HAb+ plasma sample 1. Identity of the bands was confirmed by fluorescent-labeled anti-IgG reagents. (1 represents purified standard proteins (14.4 kd to 66.2 kd), BIO-RAD; 2 represents isolated F(ab′)2 fragment of HAb+ plasma sample 1; 3 represents HAb– plasma; 4 represents IgG+ plasma 1).
