Laboratory Practices for the Detection and Characterization of Cryoglobulins and Cryofibrinogen

open access: yesJournal of Clinical Laboratory Analysis, Volume 39, Issue 15, August 2025.
This study shows the importance of carrying out the search for both cryoproteins, cryoglobulins, and cryofibrinogen in cases of strong clinical suspicion of cryoproteinemia, despite their complex but not impossible detection. Use of correct procedures from the pre‐preanalytical phase up to reporting, of alternative methods such as immunotyping and the ...

Radioimmunoassay of human plasma Lp(a) lipoprotein

open access: yesJournal of Lipid Research, 1977
A quantitative immunodiffusion assay demonstrated Lp(a) lipoprotein in 91% (911 of 1000) of subjects. In order to quantitate Lp(a) in all plasma, a sensitive and specific double antibody radioimmunoassay was developed.

A comprehensive evaluation of the heparin–manganese precipitation procedure for estimating high density lipoprotein cholesterol

open access: yesJournal of Lipid Research, 1978
The accurate quantitation of high density lipoproteins has recently assumed greater importance in view of studies suggesting their negative correlation with coronary heart disease.

The concentrations of immunoglobulins in bovine colostrum determined by the gold standard method are genetically correlated with their near-infrared prediction

open access: yesGenetics Selection Evolution, 2021
Background The quality of colostrum administered to calves is based on its concentration in immunoglobulins G (IgG, g/L). Immunoglobulins A (IgA) and M (IgM) are also present but at a lower level.

Recent Advances in the Characterization of Food Biomacromolecules: Polysaccharide, Protein, and Lipid

open access: yesFood Science &Nutrition, Volume 13, Issue 7, July 2025.
Polysaccharides, proteins, and lipids are key biomacromolecules that determine the structure, function, and nutritional value of food systems. Recent advances in spectroscopic, chromatographic, and imaging techniques have significantly enhanced our ability to characterize their complex structures and dynamic behaviors.

Mare colostrum quality and relationship with foal serum immunoglobulin G concentrations and average daily weight gains

open access: yesEquine Veterinary Journal, Volume 57, Issue 4, Page 904-914, July 2025.
Abstract Background Foals suffer from total failure to transfer passive immunity (TFTPI) when serum immunoglobulin (IgG) is <4 g/L, and partial failure to transfer passive immunity (PFTPI) when serum IgG is 4–8 g/L. Objectives To explore risk factors for poor serum IgG concentration. Study design Retrospective observational study. Methods Data from 535

Prevalence of Failure of Passive Transfer of Immunity in Dairy Calves in the Czech Republic

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2019
Prevalence of failure of passive transfer (FPT) of immunity remains relatively high worldwide. The aim of this study was to estimate the FPT prevalence in Czech dairy calves and to evaluate the selected factors – breed, herd size, sex of calves, single ...

Expression Patterns of miR‐29b and miR‐148a in Colostrum of Awassi Sheep With Higher Immunoglobulin G Levels

open access: yesVeterinary Medicine and Science, Volume 11, Issue 3, May 2025.
miR‐29b might be an important molecular target for lamb development, whereas miR‐148a could be a potential biomarker for colostrum quality. SCS and pH might be useful diagnostic parameters for IgG status. ABSTRACT This study aimed to investigate the compositional parameters and expression patterns of miR‐29b and miR‐148a in sheep colostrum containing ...

Serum immunoglobulin G subclass values in healthy Turkish children and adults

open access: yesThe Turkish Journal of Pediatrics, 1994
Immunoglobulin G (IgG) subclass levels were determined in 393 serum samples of 329 healthy children from birth to 16 years of age, 24 healthy adults and 20 pairs of mother-cord blood by radial immunodiffusion. Age-normal percentile values for IgG1,
