Custom Adjuvant Synthesis

Modern vaccines based on homogeneous subunit antigens are highly purified, which offer significant advantages over classical vaccines based on whole pathogens, enabling more precise targeting of the immune response and improved safety. However, such subunit vaccines are poorly immunogenic proteins, including feeble, short-lived immune responses. Immunoadjuvants are used to potentiate the activity of modern subunit vaccines that are based on molecular antigens. Creative Biolabs is a world leader in vaccine services and provide adjuvants for vaccines to meet different customer's demand. We offer a full range of Custom Adjuvant Synthesis services including Aluminum, Oil Adjuvant, Bacterial products, ISCOMS and more.

Adjuvants are included in sub-unit or recombinant vaccines to enhance the potency of poorly immunogenic antigens. Adjuvant development is as complex as it is a multidisciplinary intersection of formulation science, immunology, toxicology, and biology. The need for the development of safe and effective vaccine adjuvant has provided an impetus for the systematic exploration of a variety of innate immune stimuli, including small-molecule agonists of TLR2, TLR7, TLR8, nucleotide oligomerization domain 1 (NOD1), as well as C-C chemokine receptor type 1 (CCR1).

Custom Adjuvant Synthesis

Aluminium Based Minerals

The majority of currently available vaccines contain a single adjuvant, “alum” (s mixture of aluminum phosphate and aluminum hydroxide), which was introduced by Alexander Glenny in 1926. Although aluminum salts have been in widespread use and have a good safety record, they are weak adjuvants for antibody induction and induce a T helper-2 (Th2) -skewed, rather than a T helper-1 (Th1) response, an attribute that has been implicated in the rapidly waning humoral responses to re-emergence of pertussis in the USA and elsewhere in the world. Thus, more effective adjuvants are required to realize the full potential of subunit vaccines.

Oil-Based Emulsions

Saponins, which are steroids or triterpene glycosides found in many wild and cultivated crops, are popular immune stimulants for inactivated vaccines. Saponins-based adjuvants have the unique ability to stimulate cellular immunity and enhance antibody production. Ginseng, Astragalus, notoginseng and other herbs have gained attention as candidates for plant derived saponins.

Bacterial Products

Bacterial products are considered as a good source of immune adjuvants because of their potent immunostimulatory capacity. Bacterial flagellin is a potent adjuvant to CD4+ T cells in vivo. Heat shock proteins (HSPs) are highly conserved proteins whose function may play a key role in the integration of innate immunity and adaptive immunity. [1]
