Some properties of an unidentified chick growth factor found in condensed fish solubles.
In previous papers (1,2) evidence was presented to show that condensed fish solubles produced a marked increase in the growth rate of chicks on diets containing an adequate level of vitamins and essential amino acids. Berry, Carrick, Roberts, and Hauge (3) found that a water extract of fish solubles was also active in stimulating the growth of chicks. Very little other information on the proper...
متن کاملAn unidentified growth factor in the nutrition of Lactobacillus casei.
The complexity of the nutritive requirements of Lactobacillus casei is known. The organism develops slowly in synthetic or semisynthetic media such as the one described by Landy and Dicken (1942). Assay media for this organism therefore include crude supplements like peptone (Teply and Elvehjem, 1945) or trypsinized casein (Roberts and Snell, 1946). The active principle responsible for the shor...
متن کاملAn Unidentified Pleuropneumonialike Organism Isolated During Passages in Chick Embryos.
Since a large number of developing eggs are employed in the making of vaccines and the propagation of viruses and rickettsiae, it is of primary importance to detect any spontaneous -infection occurring in chick embryos, especially with' those agents that are ifiterable. In the course of passing a strain of the virus of primary atypical pneumonia amniotically in the developing chick embryo (Eato...

متن کاملDistribution of insulin-like growth factor peptides in the developing chick embryo.
Growth factors are likely to be of major significance in developmental biology. Here, the distribution of insulin-like growth factor (IGF) peptides is described during development of the chick embryo. IGF was immunolocalised using a polyclonal antibody to human IGF I detected with a modified Vectastain ABC procedure. Under the conditions used, the antibody binds strongly to IGF I and weakly to ...
