Origin
Our premium FBS is collected in approved abattoirs from herds in the United States and regular FBS
is collected in approved facilities from herds located in USDA-approved countries. In addition, we
also offer Australian source FBS and South American source FBS which are manufactured at facilities
approved by the appropriate local authorities.
Sterile Filtered
The raw pooled serum is filtered through a series of 0.1 micron sterilizing grade filters. All Corning
serum lots must test negative for mycoplasma following CFR 9CFR113.53 to qualify as
product for our customers.
Low Endotoxin Levels (LAL) Limulus Amebocyte Lysate
Each lot is tested for bacterial endotoxin. Our premium and regular grade FBS must meet a
specification of < 20.00 EU/mL and our South American grade FBS must meet a specification of < 30
EU/mL.
Low Hemoglobin Levels
A quantitative and colorimetric assay is performed to determine the residual hemoglobin
concentration in each product lot. All lots of Corning FBS are verified to contain < 30 mg/dL of
hemoglobin.
True Pooled for Consistency
True pool processing provides consistency from bottle to bottle within a lot. All sera are separated
from the collected blood by refrigerated centrifugation, true pooled, filtered, and immediately
frozen.
The filtration process consists of a series of three 0.1 micron sterilizing filters followed by a final
“polishing” filter prior to final packaging. Only raw serum that meets our strict specifications for
endotoxin, residual hemoglobin, pH, and microbial quality is approved for production. True pooling
eliminates variability within a lot.
Certificate of Analysis and Biochemical Profile
Corning sera products are analyzed for quality and performance. Testing includes pH, osmolality,
growth promotion, sterility (current USP method), mycoplasma, total protein, endotoxin and
hemogloblin levels, and viral contamination. A full biochemical profile is available for each lot upon
request.
