| [heterogeneity of ovine prolactin after labeling with iodine 125: value of labeling with lactoperoxidase]. | the authors have shown an heterogeneity of the ovine prolactine molecule after labelling with iodine 125. as well with chloramine t as with lactoperoxydase, it appears three molecular species which react with the immune serum antiprolactine (i.s.). the first species is of high molecular weight and is probably constituted of aggregates. their combination with the i.s. is non specific and give blanks of high value. the second species is a dimere and the third one is the monomere. the two last spec ... | 1976 | 140747 |

| increased atp-ase activity of lymphocytes after rosette formation with sheep red blood cells. | in a number of experiments it was demonstrated that in the e-rosette assay for human t-lymphocytes using sheep red blood cells, the atp-ase activity of the lymphocytes increased in proportion to the number of rosettes being formed. also, after increasing the number of rosettes by treatment of the sheep red blood cells (srbc) with neuraminidase and after diminishing the number of rosettes by treatment of the lymphocytes with antilymphocyte globulin (alg), change in the atp-ase activity was propor ... | 1977 | 141727 |

| a reconstituted na+ + k+ pump in liposomes containing purified (na+ + k+)-atpase from kidney medulla. | liposomes containing either purified or microsomal (na+,k+)-atpase preparations from lamb kidney medulla catalyzed atp-dependent transport of na+ and k+ with a ratio of approximately 3na+ to 2k+, which was inhibited by ouabain. similar results were obtained with liposomes containing a partially purified (na+,k+)-atpase from cardiac muscle. this contrasts with an earlier report by goldin and tong (j. biol. chem. 249, 5907-5915, 1974), in which liposomes containing purified dog kidney (na+,k+)-atp ... | 1977 | 141941 |
