Where are cell surface markers located?
the cell membrane
Cell surface markers are special proteins expressed on the surface of cells or carbohydrates attached to the cell membrane that often conveniently serve as markers of specific cell types.
What are cell surface markers?
The cell surface marker refers to the separation of fluorescent cells by flow cytometry under the detection of a fluorescence activation system using mainly the feature of the cell surface with a specific membrane protein (i.e., surface marker), which is bound by a specific antibody.
What are the different cancer markers?
There are many different types of tumour markers, including:
- alpha-fetoprotein (AFP)
- cancer antigen 125 (CA125)
- cancer antigen 15-3 (CA15-3)
- carbohydrate antigen 19-9 (CA19-9)
- carcinoembryonic antigen (CEA)
- human chorionic gonadotropin (hCG or beta-hCG)
- prostate-specific antigen (PSA)
What is a cell surface antigen Why is it important?
Why is it important? A cell surface antigen is a unique protein or glycoprotein configuration that is a distinctive marker for the recognition of a cell by the immune system. They provide the means by which the immune system distinguishes self from nonself.
What are cell identity markers made of?
Cell markers, also known as cell surface antigens, serve as monograms to help identify and classify cells. The majority of them are molecules or antigens within cell’s plasma membrane. Unique to different cell types, there exist specific combinations of markers or antigens.
What is a good cancer marker?
Examples of commonly used circulating tumor markers include calcitonin (measured in blood), which is used to assess treatment response, screen for recurrence, and estimate prognosis in medullary thyroid cancer; CA-125 (measured in blood), to monitor how well cancer treatments are working and if cancer has come back in …
