ADJUVANT PRODUCT LINE

ALHYDROGEL®

Alhydrogel® is a sterilized aluminum hydroxide wet gel suspension which has been autoclaved in bulk and aseptically filled under LAF. It tolerates re-autoclavation, but is destroyed if frozen.

When the pH is maintained at 6-8, which is normal during vaccine production, Alhydrogel® has a positive charge so they readily adsorb negatively charged antigens (e.g. proteins with acidic isoelectric points at neutral pH).
Alhydrogel® is available in three varieties: Alhydrogel® 1.3%; Alhydrogel® 2% and Alhydrogel “85″.

ADJU-PHOS®

ADJU-PHOS® is a sterilized aluminum phosphate wet gel suspension which has been sterilized by heating up to 121 degrees Celcius at 2 ATM pressure in bulk and thereafter aseptically filled under LAF. It tolerates re-autoclavation, but is destroyed if frozen.

When the pH is maintained at 6-8, which is normal during vaccine production, ADJU-PHOS® particles have a negative electrical charge so they readily adsorb positively charged antigens (e.g. proteins with alkaline isoelectric points at neutral pH).

CALCIUM PHOSPHATE

Calcium phosphate ADJUVANT is a sterilized wet gel suspension which has been sterilized by gamma-irradiation in the final container.

It tolerates autoclavation, but is destroyed if frozen.
When the pH is maintained at 6-8, which is normal during vaccine production, calcium phosphate particles have a negative electrical charge so they readily adsorb positively charged antigens (e.g. proteins with alkaline isoelectric points at neutral pH).

QUIL-A®

Quil-A® is a semi-purified extract of the sapon infraction from the cortex of the South American tree, Quillaja saponaria Molina, produced under GMP.

As a standard it is supplied as a lyophilized powder. Prior to lyophilization it has been passed through a 0.22 micron filter. Hence, the product has a very low CFU.

Quil-A® is used as a potent ADJUVANT in veterinary vaccines.
