Lipozomal Vaccine Adjuvant
(For Cloven Hooved Animals)

DESCRIPTION

Foot and Mouth Disease (FMD) is a highly contagious, outbreak causing viral disease that effects cloven-hoofed animals. The causative agent is a small RNA virus, picornavirus, with 7 serotypes. FMDV is a highly variable virus even there are variations within serotypes. The virus is mainly controlled by vaccination. Oligonucleotide containing unmethylated CpG motifs is a novel adjuvant that triggers the innate immune by Toll like receptor 9 (TLR9). Liposomal FMD vaccine is a ready to use vaccine containing lipid vesicles encapsulating oligonucleotide containing unmethylated CpG motifs and FMD serotype O antigen. Liposomal FMD vaccine is more effective than vaccines containing inactivated virus, which has some limitations such as providing short-term immune response. Liposomes, lipid bilayer vesicles, enhance biostability of entrapped molecules and act as a depot, therefore, decreases the antigen and adjuvant amount in vaccine. Also, liposomal vaccine provides long lasting protection against FMD, so higher protective immune response is developed with lower amount of antigen and adjuvant with only 2 times administration and is observed even in the first 2 weeks post-administration.

Nucleic Acid Based
Chicken Prophylactic Agent

DESCRIPTION

Nucleic Acid Based Chicken Prophylactic Agent (NABCPA) is an immunostimulatory prophylactic agent consists of synthetic unmethylated CpG motif containing single stranded DNA molecules with phosphodiester/phosphorothioate backbone structures. CpG ODN initiates signaling cascade through engagement of endosomal TLR21 and subsequently multiple immune cells are either directly or indirectly co-stimulated by the action of TLR21 mediated immune activation. CpG ODN stimulates innate immune responses of human and a variety of species including mice, sheep, cats, dogs, fish, horses and chicken. These responses can vary from species to species.
NABCPA contains CpG ODN sequences that confer optimal immune protection in chicken.
Unlike other immunomodulatory agents, NABCPA does not need any extra preparation steps such as vortexing, heating, homogenizing, sonicating and confers a ready to use prophylactic agent that can be easily prepared upon solving within PBS or Hanks buffer (pH:7.2-7.6).

TLR9L Adjuvant
(for mouse)

DESCRIPTION

The TLRL adjuvant consists of single stranded immunostimulatory sequences containing CpG motifs mimicking bacterial DNA (bDNA). Since immune cells evolved to recognize bacterial DNA and mount response against it, CpG DNA can trigger immune cells to initiate pro-inflammatory cascades. Therefore, CpG DNA recognition results in rapid and strong increase in co-stimulatory signals, and, when applied with an antigen, CpG DNA behaves as an excellent immune adjuvant to produce high titers of antigen-specific antibodies. Formulation of CpG adjuvant with an intended antigen is simple.
TLR9L-001 sequences are designed and optimized specifically to activate the immune system cells of mice.
