Quantitation of platelet-associated IgG by radial immunodiffusion [PDF]

open access: yesBlood, 1981
Abstract Platelet-associated IgG (PAIgG) was measured by a simple radial immunodiffusion technique using washed solubilized platelets and commercially available immunoplates. Subjects with normal platelet counts had PAIgG levels of 1.5--7.0 fg/platelet.

Genetic characteristics of colostrum refractive index and its use as a proxy for the concentration of immunoglobulins in Holstein cattle

open access: yesGenetics Selection Evolution, 2022
Background Colostral concentration of immunoglobulins (Ig) is crucial for the passive transfer of antibodies from the cow to the new-born calf. Direct determination of Ig by the gold standard radial immunodiffusion method is demanding in terms of time ...

Assessment of current colostrum feeding practices and passive transfer of immunity in dairy herds in Great Britain: A cross‐sectional study

open access: yesVeterinary Record, EarlyView.
Abstract Background Updated targets for measuring transfer of passive immunity (TPI) at the herd level have been suggested, but the current performance of dairy herds in Great Britain is unknown. Methods A cross‐sectional study was performed. Serum total protein (STP) data collected between October 2022 and October 2023 by 21 veterinary practices were ...

Relative Exchangeable Copper Confirms Wilson Disease and Supports Reclassification of the ATP7B p.Met665Ile Variant With Conflicting Pathogenicity Evidence

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 7, Page 1691-1695, July 2026.
ABSTRACT Wilson disease (WD) is an autosomal recessive disorder of copper metabolism caused by ATP7B mutations. Diagnosis is usually straightforward in symptomatic patients, but can be challenging in children and adolescents with mild liver disease, borderline urinary copper excretion, or inconclusive genetic findings.

Use of the ROC curves for the evaluation of the Guillain-Barré diagnostic methods

open access: yesRevista Cubana de Investigaciones Biomédicas, 2020
Introduction: The ROC (Receiver Operating Characteristic) curves are widely used to compare methods in search of greater specificity and sensitivity in which they are selected.

Effects of Prepartum Supplementation and Yeast Fermentation Products on the Progesterone‐Modulated Transfer of Passive Immunity in Bos indicus Cows

open access: yesJournal of Animal Physiology and Animal Nutrition, Volume 110, Issue 4, Page 463-473, July 2026.
ABSTRACT Inadequate colostrum intake increases risks of calf morbidity and mortality. This study investigated the effects of prepartum and early postpartum supplementation and yeast fermentation products on late‐pregnant Bos indicus cows, and the role of progesterone in mediating passive immunity transfer.

Method Comparison of Dried Blood Spot and Plasma Apolipoprotein B Measurement on a Semi‐Automated Analyser: Toward Accessible Lipid Profiling in Resource‐Limited Settings

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Apolipoprotein B (ApoB) is a key marker of atherogenic lipoprotein burden, but conventional plasma‐based testing requires venous sampling and centralized laboratory infrastructure. Dried blood spot (DBS) sampling offers a minimally invasive alternative suitable for decentralized settings.

A parallel evaluation of 5 indirect cost-effective methods for assessing failure of passive immunity transfer in neonatal calves

open access: yesJDS Communications, 2020
The aim of this study was to evaluate the diagnostic accuracy of 5 indirect methods that may be used in veterinary practices to assess the success of maternal immunoglobulins transfer in neonatal calves.

Risk Factors for and Prevalence of Failure of Passive Transfer of Immunity in Calves on Dairy Farms in Türkiye

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
The prevalence of FPTI in this study was similar to reports internationally. This research shows that there were both modifiable and non‐modifiable significant risk factors for FPTI in Türkiye dairy herds, specifically colostrum feeding method and season of birth and herd size, dam parity and calf breed.

Effect of storage on the measurement of apolipoproteins A-I and A-II by radial immunodiffusion

open access: yesJournal of Lipid Research, 1980
We studied the effect of storage time and conditions on the measurement of apolipoprotein A-I and A-II by radial immunodiffusion. Purified A-I and A-II standards were stable for at least 6 months before any change in immunoreactivity was detected if ...
