Ovotransferrin dosage

Ovotransferrin is a glycoprotein naturally present in egg white, belonging to the transferrin family. It plays a key role in antimicrobial defense, limiting the availability of iron necessary for the development of microorganisms. Due to its functional properties, ovotransferrin is studied and valued in several fields, including the food industry, animal health, and nutraceutical formulations.

Ovotransferrin measurement allows for the assessment of the nutritional and functional quality of egg-derived products, as well as for verifying the consistency of protein powders and ingredients used in dietary supplements. This analysis is also relevant for the development of formulations enriched with bioactive proteins, with benefits for intestinal, immune, or antimicrobial health.

Analytical methods

Several approaches can be used to quantify ovotransferrin:

• The ELISA method, based on specific antibody recognition, is suitable for rapid and sensitive analyses. It is widely used in routine monitoring or research studies.
• High-performance liquid chromatography (HPLC) offers a complementary approach, enabling precise protein separation and reproducible quantification in complex matrices.

Both methods are reliable and can be chosen depending on the type of matrix, the level of sensitivity required and the objectives of the analysis.

Affected matrices

The ovotransferrin assay is applicable to different types of samples:

• Fresh or processed egg whites
• Egg protein powders
• Food supplements enriched with animal proteins
• Innovative products incorporating bioactive ingredients from eggs

Industrial applications

Ovotransferrin analysis addresses several issues:

• Quality control of egg-based food products to ensure their nutritional value and biological activity.
• Development of nutraceutical formulations integrating bioactive proteins recognized for their antimicrobial and immunomodulatory effects.
• Valorization of poultry industry co-products into high value-added functional ingredients.
• Animal health research, where ovotransferrin is studied as a nutritional indicator or as a functional molecule to strengthen the intestinal health of animals.

Additional analyses

The ovotransferrin assay can be complemented by other analyses available in the YesWeLab catalog, such as the assay of lysozyme, another bioactive egg protein, the assay of total proteins, or the analysis of free amino acids. For food and nutraceutical formulations, it may also be relevant to combine these analyses with the assay of lactoferrin, a glycoprotein with similar properties used in animal nutrition and health.

Regulations and quality

Analytical monitoring of bioactive proteins such as ovotransferrin helps meet the quality and traceability requirements set by European regulations. In the context of the valorization of functional ingredients, the standardization and precise quantification of these proteins are key elements in ensuring the safety and efficacy of finished products.
