When a carrier-hapten complex was used to raise antibodies in rabbits against ceramidetrihexoside, an antiserum was obtained in which the activity against the carrier could not be removed by absorption with the carrier without loss of the anti-hapten activity.2. Antibodies against ceramidetrihexoside were raised in rabbits by immunizing them with a mixture of bovine serum albumin and the glycolipid according to Hakomori (1972). It was found that these antibodies cross-reacted with digalactosylceramide. but not with lactosylceramide or digalactosyldiglyceride. No cross-reactivity was observed with globoside in an artificial membrane system but a slight cross-reactivity was found with globoside absorbed on cholesterol microcrystals. A possible explanation for the latter phenomenon is discussed. From inhibition studies with different sugar compounds combined with the cross-reactivity studies, it can be concluded that anti-ceramidetrihexoside antibodies have a high and strict specificity for a terminal galactosyl α(1→ 4)galactosyl group.3. Antibodies raised in rabbits against globoside by the method of Hakomori (1972) did not cross-react with the other glycolipids tested. The characteristics of these antibodies are compared with those of the anti-ceramidetrihexoside antibodies.4. A human anti-P1,P,Pk serum from a person with the rare phenotype p, which contains anticeramidetrihexoside (anti-Pk) activity was compared with the rabbit anti-ceramidetrihexoside serum. The two antisera showed very similar characteristics with regard to the anti-ceramidetrihexoside activity.</div>","PeriodicalId":13265,"journal":{"name":"Immunochemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1978-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0161-5890(78)90130-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11900789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Partial purification of papain solubilized antigen by gel filtration and lectin affinity chromatography yielded material that was 50% precipitable by a specific rabbit antibody reagent obtained from antiserum raised against the tumor.

Conjugates of bovine serum albumin with trinitrophenyl. dinitrophenylsulfonic and sulfanilic acids were used as inhibitors (TNP24BSA, DNP23BSA, Sulf17BSA).The spleen TNP-RFC content in BALB/c mice was 60% higher than in the C57BL/6 strain. F1 hybrids were intermediate in this respect. F1 × BALB/c hybrids had on the average 35% more TNP/RFC than F1 × C57BL/6 mice.The TNP-RFC inhibition (avidity) curves obtained with TNP24BSA, DNP23BSA and Sulf17BSA were markedly different in BALB/c, C57BL/6 and (BALB/c × C57BL/6)F1 animals. We conclude that the spleen content and avidity of TNP-RFC in mice are subject to strict genetic control.Assuming random expression of V (idiotype?) genes, the present results seem to indicate that the content and proportions of groups of B clones are controlled by structural immunoglobulin genes.

Alternate procedures for the purification of i-antigen were developed using ion-exchange chromatography. While certain of these procedures result in a homogeneous preparation of i-antigen, the poor yields obtained make these procedures impractical. An alternate method for the purification of i-antigen was developed using immunoaffinity chromatography. Purification by this technique proved to be superior to the various standard procedures described previously. The immunoaffinity column is rapid and results in a recovery, on the average, of over 95% of the applied material. The columns are readily regenerated and may be used numerous times without loss of capacity or purification ability. The i-antigen purified by this method appears homogeneous immunologically and electrophoretically on polyacrylamide gel electrophoresis and isoelectric focusing.</div>","PeriodicalId":13265,"journal":{"name":"Immunochemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1978-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0161-5890(78)90133-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11900794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
