While the production process is somewhat involved, the resulting immune response can surpass that induced by Freund's complete adjuvant. Sold in 25 gram amounts, however small gratis amounts are available. While the co-precipitation procedure is not difficult, it requires some manipulation. The cost is negligible. Available from numerous chemical companies.
Small aliquots are available upon request from the producer.
AdjuPrime - this is a carbohydrate polymer marketed as an alternative to Freund's complete adjuvant. Independent studies comparing its efficacy to other adjuvants do not appear to be available. The nitrocellulose is inert and causes minimal inflammatory response. It therefore requires frequent boosting to achieve a high-titer response, but produces minimal inflammatory response. Gerbu adjuvant is available from C-C Biotech, Poway, California.
