Blood groups in sheep.
The A reagent: The A reagent (Table 1 ) was an unabsorbed, isoimmune antiserum. It was produced in a sheep named A, which received five intrajugular injections, at five-day intervals, of 5 ml of citrated blood from a sheep named B. The antiserum was collected five days after the last injection. Sheep A was of blood-group R in the R 0 system, and a preimmunization sample of her serum contained n...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Inheritance of R-o-i Blood Groups and Alkaline Phosphatase Polymorphism in Sheep.
RENDEL and STORMONT (1964) found that in sheep sera subjected to starch-gel electrophoresis the zone of phosphatase activity which they designated B is highly correlated with the presence of soluble blood-group substance 0 in adult females. Since the presence of 0 substance is recessive to the presence of R substance ( STORMONT 1951 ; RENDEL, NEIMANN-SBRENSEN and IRWIN 1954), they inferred that...
متن کاملThe F-v and Z Systems of Bovine Blood Groups.
VIDENCE for two extensive series of alleles effecting blood groups in E cattle has been given in a previous report ( S T ~ ~ ~ ~ O N T , WEN ant1 IRWIN 1951). The two systems of blood groups are called R ;uid c’. Over 80 alleles are now recognized in the R series. The 1: alleles control so-callet1 “ groups ’’ or ’* inherited combinations ” of a niininiuni of 21 hlood factors. For example, the R...
متن کامل$z^circ$-filters and related ideals in $C(X)$
In this article we introduce the concept of $z^circ$-filter on a topological space $X$. We study and investigate the behavior of $z^circ$-filters and compare them with corresponding ideals, namely, $z^circ$-ideals of $C(X)$, the ring of real-valued continuous functions on a completely regular Hausdorff space $X$. It is observed that $X$ is a compact space if and only if every $z^circ$-filter ...
