February 26, 2009

PRODUCT / LOT NUMBER:

Antibody Screen Wash with De-ionized Water, Software Version 3.1

REASON:

Biotest discovered that in rare instances, antibody screen testing may be washed using de-ionized water (System Liquid) instead of the intended Phosphate Buffered Saline (PBS, Wash Solution).
