Glycophorin-A
Use
Glycophorin A is a major sialoglycoprotein present on human precursor and mature red blood cells. This marker is useful in characterizing erythroid cell development as well as diagnosing erythroid leukemia.
Special Instructions
Specimens may be fixed in formalin for 24-72 hours by collection sites, then transferred to 70% ethanol and stored at 2-8°C for longer-term storage if needed. Samples must be tested within 3 months after placing in ethanol. Positively charged glass slides are required to prevent background staining and prevent tissue loss. Slides should be left unbaked.
Limitations
The test is conditioned upon the requirement that specimens must be fixed in 10% NBF or B plus. All other fixatives will be rejected.
