Biochemical Characterization of an In-House <em>Coccidioides</em> Antigen: Perspectives for the Immunodiagnosis of Coccidioidomycosis

Molecules, 2012
The objective of this study was to evaluate the reactivity of an in-house antigen, extracted from a strain of <em>C. posadasii </em>isolated in northeastern Brazil, by radial immunodiffusion and Western blotting, as well as to establish its ...

Determining the IgG concentrations in bovine colostrum and calf sera with a novel enzymatic assay

Journal of Animal Science and Biotechnology, 2018
Background Immune protection in newborn calves relies on a combination of the timing, volume and quality of colostrum consumed by the calf after birth. Poor quality colostrum with inadequate immunoglobulin concentration contributes to failed transfer of ...

Determination of B protein of low density lipoprotein directly in plasma.

Journal of Lipid Research, 1975
Quantitation of the apoprotein constituents of lipoproteins has extended our knowledge of plasma lipid transport. Previously, B protein content of low density lipoprotein could be measured by radial immunodiffusion only after ultracentrifugation. However,

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

Blood, 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

Genetics 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 ...

Two New Kindreds with Complete Factor D Deficiency. [PDF]

Eur J Immunol
The complement system plays a crucial role in immune defense, and factor D deficiency is a rare immunodeficiency associated with life‐threatening bacterial infections. We report two new cases of complete factor D deficiency, including the first described in a Down syndrome patient, highlighting the need to investigate complement deficiencies in ...

Single Radial Immunodiffusion of Undiluted Serum Proteins

Clinical Chemistry, 1972
Abstract A simple method is described for quantitative determination of IgG, IgA, IgM, α2M, and other proteins without dilution of the sample. Strips of gelatinized cellulose acetate spread with antiserum are used as a supporting medium. The method is accurate, highly reproducible, and seems particularly suitable for routine work because

Risks for human health related to the presence of plant lectins in food

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The European Commission asked the European Food Safety Authority (EFSA) to assess the risk related to the presence of plant lectins in food. Based on the available evidence, the CONTAM Panel considered only phytohaemagglutinin (PHA), a legume lectin from beans (Phaseolus sp.), for the risk characterisation.
