Abstract

We have used a rabbit antiserum prepared against purified rat β2µ-microglobulin to immunoprecipitate molecules from lysates of radioiodinated murine thymocytes and splenocytes. All the molecules that are reactive with this serum have subunits of 44,000 and 12,000 and can be identified as H-2 and TL antigens. Thus, the anti-β2µ serum can deplete lysates of the majority of the TL and H-2 antigens which can be subsequently recognized by alloantisera. If TL and H-2 are precipitated from the lysates before the addition of anti-β2µ, no preactive molecules remain. Our results indicate that Ia antigens cannot be depleted from the lysates with anti-β2µ. The studies also suggest that TL and H-2 heavy chains can exist as beth monomers and dimers. These observations are discussed with regard to previous studies concerning the native structure of H-2 and TL antigens.
