  • The cationized form of BSA (cBSA) is highly positively charged protein with significantly increased immunogenicity. (wikipedia.org)
  • Consequently, the haptens themselves are nonimmunogenic and they cannot evoke an immune response until they bind with a larger carrier immunogenic molecule. (wikipedia.org)
  • Antibodies against small molecule haptens enable robust and rapid detection, monitoring and quantification using assays such as ELISA or IHC/IF. (prosci-services.com)
  • however, there can be challenges in conjugating the small molecule to a carrier protein and then generating the desired immune response specific to the small molecule and not the carrier protein or linker. (prosci-services.com)
  • We recommend analyzing the immunogenic variables of the small molecule hapten and application of interest since each application presents antigens in a distinct way. (prosci-services.com)
  • These immunogenic variables include the chemical structure, conjugation method, cross-linking between the small molecule and protein carrier, the orientation of the hapten on the carrier protein, and linkers used. (prosci-services.com)
  • An antigen is any substance, such as a molecule, moiety, foreign particulate matter, or allergy, that induces the immune system to create antibodies against it. (biomedres.us)
  • This antibody and its recombinant constructs were able to recognize proteins of Loxosceles spider venoms with specificity. (bvsalud.org)
  • However, from the cellular perspective, after binding of hapten to a carrier protein and formation of the complexes that are processed inside Antigen Presenting Cells (APCs) and presented as a stable hapten-peptide complex to the major histocompatibility complex class II (MHC II) settled in the tissues, an immune response will begin [13]. (biomedres.us)
  • Generally, administration of adjuvants is used both in experimental immunology and in clinical settings to ensure a high quality/quantity memory-enhanced antibody response, where antigens must be prepared and delivered in a fashion that maximizes production of a specific immune response. (wikipedia.org)
  • The carrier proteins, once coupled to the peptides, provide these additional motifs and generate a strong antibody response. (gbiosciences.com)
  • The use of cationized BSA is known to elicit greater immunogenic response compared to normal BSA (1-3). (gbiosciences.com)
  • An immunogen can be defined as a complete antigen which is composed of the macromolecular carrier and epitopes (determinants) that can induce immune response. (wikipedia.org)
  • The hapten-carrier complex, unlike free hapten, can act as an immunogen and can induce an immune response. (wikipedia.org)
  • The purpose of this article is to share information with researchers and clinicians about creating a vaccine by incorporating a specific substance of abuse in a hapten conjugate that triggers an immune response against the effect of the drug. (biomedres.us)
  • By 1988, this vaccine was replaced by the more immunogenic conjugate vaccines. (medscape.com)
  • Findings from numerous studies in animals and children demonstrate that the HiB conjugate vaccines have immunologic properties characteristic of T-cell-dependent antigens. (medscape.com)
  • From the chemical standpoint, the hapten is a low molecular weight chemical agent, that must bind to a large carrier protein to create a conjugate (Figure 1), before being detected by the immune system and eliciting an immunological response. (biomedres.us)
  • Tolerance induction in B lymphocytes but thymus-dependent antigens. (wikidata.org)
  • In this work, we present mannan-coated protein NPs, incorporating antigen proteins for antigen-specific tolerance induction. (bvsalud.org)
  • Because of its evolutionary distance from mammals, high molecular weight and complex structure it is usually immunogenic in vertebrate animals. (wikipedia.org)
  • Keyhole limpet hemocyanin is a widely used carrier protein due to its large molecular mass (4.5x105-1.3x107Da aggregates) and large number of primary amines that can react with cross-linkers for the coupling of peptides. (gbiosciences.com)
  • Although we previously reported an affinity maturation strategy in which the association rate of the antibody toward its antigen is improved by introducing a cluster of arginine residues into the framework region of the antibody, the detailed molecular mechanism responsible for this improvement has been unknown. (bvsalud.org)
  • In this study, we introduced five arginine residues into an anti-hen egg white lysozyme antibody (HyHEL10) Fab fragment to create the R5-mutant and comprehensively characterized the interaction between antibody and antigen using thermodynamic analysis, X-ray crystallography, and molecular dynamics (MD) simulations. (bvsalud.org)
  • Here, the NPs were formed spontaneously via heat denaturation of three component proteins: an antigen protein, human serum albumin (HSA) as a matrix protein, and mannoprotein (MAN) as a targeting ligand for dendritic cells (DCs). (bvsalud.org)
  • Keyhole limpet hemocyanin It is copper-containing respiratory protein, isolated from keyhole limpets (Megathura crenulata). (wikipedia.org)
  • Nanoparticles (NPs) for allergen immunotherapy have garnered attention for their high efficiency and safety compared with naked antigen proteins. (bvsalud.org)
  • The heat-induced formation of protein NPs is a one-pot preparation method and can be applied to various proteins. (bvsalud.org)
  • We applied this method to various antigen proteins and found that the self-disperse after heat denaturation was a requirement for incorporation into the NPs. (bvsalud.org)
  • The MAN-coated NPs proposed here, prepared by a simple method, have the potential for effective and safe allergies treatment for various antigens. (bvsalud.org)
  • In addition, the antigen presentation should mimic the same orientation as the assay. (prosci-services.com)
  • Ovalbumin Also known as egg albumin, OVA is the main protein (60-75%) found in hen egg white. (wikipedia.org)
  • Our results indicate that introduction of charged residues strongly enhanced the association rate, as previously reported, and the antibody-antigen complex structure was almost the same for the R5-mutant and wild-type Fabs. (bvsalud.org)
