Seven cases of an abnormality in bovine transferrins are described. In this abnormality the two fastest strong protein bands apparently have the same mobility as the two slow bands. It has been seen in Tfa2, Tfd1, and Tfd2 transferrins. The characteristic which has only been found in the Hereford breed could be explained by a recessive epistatic gene affecting the sialic acid binding to the two faster strong protein bands of the four controlled by each Ifallele.

Foetal and neonatal transferrins in cattle.
TLDR
Homozygous transferrins of adult cattle are made up of two strong pairs and one weak pair of protein bands on starch gel electrophoresis and the ai protein, which is present in early foetal life and almost disappears by 250 days of embryonic development, shows individual variation.
Isolation and properties of individual components of cattle transferrin: The role of sialic acid
TLDR
The results of sialic acid assays showed that the difference between the pairs of bands was caused by differing numbers of sIALic acid residues (0–5) per molecule of protein, but that siali acid was not responsible for the differences between the bands within a pair.
Studies on bovine transferrin; isolation and partial characterization
TLDR
Sedimentation and viscosity data in concentrated urea suggest that bovine transferrin is composed of two subunits, an observation which is in contrast to data from studies which suggest that human transferrin was composed of a single polypeptide chain.
The equine protease inhibitory system (Pi): Abnormal expressions of PiF, PiL, and PiS
Three cases of abnormal expression of the equine protease inhibitory alleles, Pi F, L, and S1, were observed following the examination of 30,000 plasma samples by one-dimensional acid (pH 4.6)…
Serum albumin and transferrin variants in italian water buffalo (Bos bubalis L.)
TLDR
Le tre varianti (AlbA, AlbAB, AlbB) dell'albumina sono controllate dai geni codominanti AlbA ed AlbB e le tre variante (TfD, TfDE, TFE) delle transferrine dai due alleli dominanti TfD e TfE.

TLDR
The transferrins in Swedish cattle were studied and a formula is given for the possibility of making exclusions in parentage testing and the value of the transferrin types in diagnosis of zygosity in cattle twins is shown.
Subdivision of the allele Tfd for transferrins in Holstein and Ayrshire cattle.
TLDR
Evidence is presented which indicates that the former TfD allele is, in fact, two alleles which produce different transferrins which were indistinguishable using the original starch-gel electrophoresis procedures.
THE EFFECT OF SIALIDASE ON PIG TRANSFERRINS.
TLDR
The mobility differences between the three zones observed for both TfA and TfB under high voltage Tris–citrate gel analyses do not appear to be due to the amount of sialic acid possessed by each.
Alterations in Sialic Acid Content of Human Transferrin
TLDR
Starch gel electrophoresis of human transferrin treated with neuraminidase revealed a pattern of five bands whose intensities varied with neuraminaidase concentration, which suggested that the bands represented the stepwise removal of sialic acid from the transferrin molecule.

Improved technique for separation and identification of bovine beta globulins by starch-gel electrophoresis.
TLDR
By the use of a buffer solution of pH 7.3–7.35 for the preparation of the gel for starch-gel electrophoresis, it was shown that each transferrin allele produces six distinct protein bands, and it was demonstrated that this modification facilitates the differentiation between transferrin types whose bands migrate very close to each other in starch- gel electrophoreis.

A preparation of a readily available sialidase of established purity and specificity was obtained from C. perjringens, and its properties are compared with the well defined V. cholerae enzyme isolated by Ada, French, and Lind.
