Used in research settings to quantify folic acid-binding protein levels in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables detection and measurement of FBP concentrations, supporting studies related to folate metabolism, nutritional status, and conditions like folate deficiency or neural tube defects. It is also applied in reproductive health research, as FBP is present in high levels in seminal fluid and plays a role in sperm function and fertility assessment. The assay is not for diagnostic use but supports biomarker validation and preclinical investigations.
