What are cytokines?
Cytokines are signaling molecules that mediate and regulate immunity, inflammation, and hematopoiesis.
Why use tear samples for cytokine analysis?
Tear samples provide a non-invasive way to study ocular health and disease.
What is a bead-based multiplex assay?
It is a technique that allows simultaneous detection of multiple analytes in a single sample.
How are tear samples collected?
Tear samples can be collected using Schirmer Strips, which absorb tears from the eye.
What is the advantage of using small sample volumes?
Using small sample volumes minimizes discomfort for subjects and allows for more efficient use of precious samples.
Who demonstrated the procedure in the study?
The procedure was demonstrated by Praveen Balne, a post-doc from the lab.
