2. “Our Glucose Oxidase is
tried, tested and proven to
perform in blood glucose
monitoring 5 BILLION
times every year”
BBI’s Glucose Oxidase is the key component
in over 5 billion blood glucose monitoring
test strips every year
But what makes it so good?
 Highest levels of activity and purity –
increase speed and accuracy
 Multiple high purity grades available –
optimise your assay, save money
 Proven performance – meeting latest
FDA accuracy guidelines (+/- 15%)
 Batch to batch reproducibility and
consistency – essential in high volume
strip production
Number 1 supplier of Glucose Oxidase

3. Why use our FAD-GDH?
 Not affected by variations in oxygen levels
 Optimised purification method - fewer
contaminants, reduced backgrounds = better
sensitivity
 Improved performance for hospital based
systems
 Good stability
 70% of activity remaining after 90 days at
50ºC
 Stable below -20ºC for at least 24 months
 No additives or animal derived materials
present
“Did you know we also
supply an FAD dependent
Glucose Dehydrogenase
(FAD-GDH)?”
FAD dependent Glucose Dehydrogenase

4. Better sensitivity with FAD-GDH
Our FAD-GDH’s high purity leads to a lower background signal, which enables you to
measure lower glucose concentration levels – resulting in better sensitivity

5. Our next generation FAD-GDH is ideal for
customers looking to develop a product of
greater accuracy to meet tightening
regulatory requirements.
But what makes it so good?
 Increased accuracy through improved
specificity to glucose
 Higher reactivity, providing a faster signal
 Improved stability, enhancing reliable
strip performance
 Cost savings, requiring fewer units of
enzyme per strip
NEW FAD-GDH – reduced xylose interference
“We offer a service and
range of products
unique to the biosensor
market”

6. Improved specificity using GLD3
GLD1 GLD3
D (+)-Glucose: 100% 100%
D (+)-Galactose: 0.41% 0.27%
D (+)-Maltose: 0.30% 0.67%
D (+)-Mannose: 4.50% 1.73%
D (+)-Xylose: 12.40% 1.60%
2-deoxy-D-glucose: 43.20% 39.8%
Specificity was measured by substituting different sugars (concentration 200mM) for glucose
in the BBI FAD-GDH assay.

7. Highest quality enzyme labels
Use the highest quality Alkaline Phosphatase and be confident in
the results
 Highest activity ALP on the
market: >2200 glycine U/mg
protein and >7000 DEA U/mg
protein
 High stability: less than 10%
activity lost over 48 months
 Benchmarked data: showing
proven performance against
the competition

8. Highest quality enzyme labels
Be confident in achieving better and consistent HRP conjugation
 High isozyme C content
(available above 90%)
 High activity levels ~280 U/mg
with some batches achieving
>300 U/mg
 Highly available amino groups
for clean conjugation
 Planned purchase of
horseradish roots gives a
controlled and consistent supply

9. Urease for clinical chemistry and biosensors
