quality control information
product name: influenza b antigen
bioar performs quality control tests to ensure each batch meets in-horse specification. it is important that each user perform titrations of antigen using their own assay as each format and serum release panel makes different performance demands on the antigen.
test:
hemaglutination endpoint assay:
result: 27,000 ha units/ml
protein concentration: protein is determined using the dye binding assay in the microassay format. the standard curve is generated with a known concentration of igg.
result: 1.56 mg/ml
inativation assay: the effectiveness of inactivation is determined when no detection of growth in two blind passages under optimal culture conditions. no live virus detected by either cpe or ha assay.
result: no growth detected
