Genetic control of immunoglobulin allotypes in the fowl

Eight immunoglobulin allotypic specificities have been identified in the fowl by isoimmunization. Aa1 and Aa2 are controlled as codominants at the a locus, Ab1 and Ab2 at the b locus, and Ac1, Ac2, Ac3, and Ac4 at the c locus. Column chromatography and ultracentrifugation indicate that the specificities at the a locus are located on molecules corresponding to IgG with sedimentation coefficients 7 S. Immunoelectrophoresis results also indicate that we are dealing with an immunoglobulin G molecule. Further tests are underway to resolve this beyond doubt.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44156/1/10528_2004_Article_BF00520354.pd

How to Hash into Elliptic Curves

We describe a new explicit function that given an elliptic curve $E$ defined over \FF_{p^n}, maps elements of \FF_{p^n} into $E$ in \emph{deterministic} polynomial time and in a constant number of operations over \FF_{p^n}. The function requires to compute a cube root. As an application we show how to hash \emph{deterministically} into an elliptic curve
