What is HER2?
HER2 is a protein that can promote the growth of cancer cells. It is often overexpressed in certain types of breast cancer.
How does the sandwich ELISA work?
The sandwich ELISA uses two antibodies to capture and detect the target protein, allowing for precise quantification.
What samples can be used with this assay?
The assay can be used with in vitro cultured cells, blood, and tissue samples.
Why is this assay important?
It provides a validated method to measure HER2 levels, which is crucial for diagnosis and treatment of HER2-positive cancers.
Can this assay be used in clinical settings?
Yes, the assay is designed for both research and clinical diagnostics.
