“…HOLTER, LANZ, and LINDERSTR~M-LANG (1938) found an equal distribution of alanylglycine dipeptidase activity to the first eight blastomeres in the case of Psammechinus miliaris; further, HOLTER and LINDAHL (1941) found that there was no accumulation of dipeptidase activity in the animal or vegetal halves of the blastula, nor in the ectoderm, endoderm, or mesoderm of the gastrula of Paracentrotus lividus.…”

“…The technic has already been applied to the determination of peptidase activity (44) and it is being adapted for use with other enzymes. An investigation of the peptidase activity of single blastomeres of sea-urchin eggs in the eight-cell stage has been completed (45). The composition of the drops used in the peptidase method is: 0.1 m. to c/Lalanylglycine, 0.0173 M to NaOH, 0.0333 m. to phosphate buffer of pH 7.4, in enzyme solution.…”

Journal the methods and applications of enzyme studies in histological chemistry by the Linderstrpm-Lang Holter technic (1). In recent years the technic designed by Linderstr0m-Lang and Holter at the Carlsberg Laboratory in Copenhagen has been expanded considerably by them and their collaborators, who come from many parts of the world to learn and to help further the histochemical studies in the * It was erroneously stated in the previous paper (I) that the apparatus was available from the Burrell Technical Supply Company, Fifth Avenue, Pittsburgh, Pennsylvania, The apparatus, including the new ultramicro equipment, may be obtained from E.

ONE FIGURE INTROD~JCTI ONAn investigation by Holter, Lam and Linderstrdm-Lang ('38) of the peptidase distribution among the blastomeres formed by the first cleavages of eggs of Psammechinus niiliaris disclosed an equal distribution within the limits of experimental error of the dilatometric method (Linderstrdm-Lang and Lanz, '38) used. The embryos examined were in the 8-cell stage, and both the animal and vegetative halves, separated by a cut along the third cleavage plane, as well as the single blastomcres, contained only slightly different amounts of peptidase, although their morphological developmental potentialities undoubtedly a r e different.
