FACS May Employ Which All the Following EXCEPT

Question

FACS may employ which all the following EXCEPT:
A)laser fluorescence detector
B)fluorescently labeled antibodies
C)gfp promoterless gene constructs
D)laser probe to destroy unlabeled cells
E)differential flow to move cells to a variety of end containers

Accepted Answer

FACS does not employ a laser probe to destroy unlabeled cells. It uses a laser fluorescence detector to detect labeled cells, fluorescently labeled antibodies to bind to specific markers on cells, and GFP promoterless gene constructs to study gene expression. It also utilizes differential flow to sort cells into different containers based on their characteristics.
