Research demonstrates improved isolation and purification of alpha macroglobulin in rats, suggesting enhanced methods for protein study.

The research aims to isolate and characterize rat α₁ and α₂ macroglobulin and to develop specific antibodies against them.
Isolation of α₁ and α₂ macroglobulin from rat serum using gel filtration, zonal centrifugation, and ion exchange chromatography.
Characterization of proteins through various electrophoresis techniques and determination of nitrogen content.
Development and purification of antibodies in goats using ammonium sulfate precipitation and ion exchange.
Improved isolation technique enhanced the purity and yield of α₁ and α₂ macroglobulin.
Notable differences were observed in mobilities and subunit sizes of the proteins during electrophoresis.
Development of specific antibodies showed positive titers in goat serum, though further purification attempts were unsuccessful.

William L. Thompson (1978) studied this question.
