Summary <strong>of</strong> presentation<br />
• New capture detection method for quantitation<br />
• Correlation with <strong>SRID</strong><br />
• Stability indicating<br />
• Timelines<br />
• Extended life <strong>of</strong> reagents<br />
• NA quantitation - progress
<strong>Quantitation</strong> <strong>of</strong> vaccine antigen (HA)-<br />
Single radial Immunodffusion<br />
• Antibody in a 1% agarose gel<br />
with detergent<br />
• Antigen loaded into well<br />
• Detects immuno-relevant<br />
material
Single radial Immunodffusion – approved<br />
method<br />
•Time consuming<br />
•~20% coefficient variation<br />
• Low sensitivity<br />
• Lab to Lab variation<br />
• Unable to be automated<br />
• frequent delays for reagents<br />
(antigen and antiserum)<br />
