title: Presence of soluble SLA histocompatibility antigen in pig plasma.
abstract: The major histocompatibility antigens of the pigs (SLA 1 and SLA 15) were solubilized by papain and then iodinated according to Greenwood's chloramine T method. These antigen preparations were used in radioimmunoassays for the detection of soluble inhibitors in pig plasma. Specific soluble substances were demonstrated in addition to a certain amount of cross-reactivity with other so far unidentified antigens.
