Serum quality: an analysis of its components.

This research article studies and analyzes the components of various types of sera: foetal and new born bovine (calf) serum, horse serum, human serum and human plasma, and protein solutions made from human plasma by-products.

Study of Different Types of Sera

The research conducted aimed at understanding the various components of different types of sera. The subjects of this study included:

• Foetal and newborn bovine sera
• Horse serum
• Human serum and human plasma
• Protein solutions prepared from by-products of human plasma fractionation

Comparison of Components in Different Sera

During the analysis, the research found differing levels of certain compounds in the sera.

• Foetal bovine sera had lower total protein (g/l) and gamma-globulin percent than the other types of sera studied. In simpler terms, newborn calf blood had lower levels of total proteins and a specific type of protein (gamma-globulin) when compared to the others.
• Potassium levels (mmol/1) were found to be higher in foetal bovine sera. This indicates that the blood of newborn calves contained more potassium than the other sera in the study.

Detection of Protease Inhibitors

All samples tested in this study were found to contain protease inhibitors. Protease inhibitors are substances that block the activity of proteases, enzymes that break down proteins. This means that, in all the different types of sera examined, elements were present that prevent the breakdown of proteins. This detail regarding the presence of protease inhibitors broadens our understanding of the constituents and functionality of these sera.
