Adjuvants – Description and Types Available
- Adjuvants are compounds or chemicals that can be added to immunizing peptides in order to promote and stimulate the immune response.
- Ribi adjuvants are oil-in-water emulsions.
- Specol adjuvant is water in purified mineral oil.
What are the types of adjuvants?
2.1. Types of adjuvants
| Adjuvant | Composition | Receptor targeted |
|---|---|---|
| Aluminum | One or more of the following: amorphous aluminum hydroxyphosphate sulfate (AAHS), aluminum hydroxide, aluminum phosphate, potassium aluminum sulfate (Alum) | T helper cell, NLRP3 and other innate immune cells |
What type of adjuvant is alum?
Aluminum-containing adjuvants usually referred as Alum are considered as T helper type-2 (Th2) adjuvants, while agonists of toll-like receptors (TLRs) are viewed as adjuvants that favor Th1/Th17 immunity.
What are adjuvants what are their types and importance?
Adjuvants can be defined as substances that increase immunogenicity of a vaccine formulation when added/mixed to it. The choice of the adjuvant is of utmost importance as it can stimulate strong humoral and cell mediated immunity indispensable for protection against some pathogens.
What are adjuvants Name any two adjuvants?
There are many known adjuvants in widespread use, including aluminium salts, oils and virosomes.

How do adjuvants work?
Adjuvants may act by a combination of various mechanisms including formation of depot, induction of cytokines and chemokines, recruitment of immune cells, enhancement of antigen uptake and presentation, and promoting antigen transport to draining lymph nodes.
What is a chemical adjuvant?
An adjuvant is a substance that is added to a pesticide product or pesticide spray mixture to enhance the pesticide’s performance and/ or the physical properties of the spray mixture.
What are adjuvants example?
Adjuvants augment, stimulate, potentiate, enhance, activate, or modulate the immune response at either cellular or humoral level. Best known examples include Freund’s adjuvant, Bacillus Calmette–Guérin (BCG), Corynebacterium parvum; all of which contain bacterial antigen.
What is a adjuvant?
An adjuvant is an ingredient used in some vaccines that helps create a stronger immune response in people receiving the vaccine. In other words, adjuvants help vaccines work better.
What are adjuvants made of?
An adjuvant is a substance added to some vaccines to enhance the immune response of vaccinated individuals. The aluminum salts in some U.S. licensed vaccines are aluminum hydroxide, aluminum phosphate, alum (potassium aluminum sulfate), or mixed aluminum salts.
