Project description:Current seasonal and pre-pandemic influenza vaccines induce short-lived predominantly strain-specific and limited heterosubtypic responses. To better understand how vaccine adjuvants AS03 and MF59 may provide improved antibody responses to vaccination, we interrogated serum from subjects who received 2 doses of inactivated monovalent influenza A/Indonesia/05/2005 vaccine with or without AS03 or MF59 using hemagglutinin (HA) microarrays (NCT01317758 and NCT01317745). The arrays were designed to reflect both full length and globular head HA derived from 17 influenza A subtypes (H1 to H16 and H18) and influenza B strains. We observed significantly increased strain-specific and broad homo- and hetero-subtypic antibody responses with both AS03 and MF59 adjuvanted vaccination with AS03 achieving a higher titer and breadth of IgG responses relative to MF59. Adjuvanted vaccine was also associated with the elicitation of stalk directed antibody. We established good correlation of the array antibody responses to H5 antigens with standard HA inhibition and microneutralization titers.
Project description:To identify differentially phosphorylated proteins between wild-type and Pak1-deficient mouse breast cancer cells, we performed a comparative study by using phospho-antibody arrays.
Project description:We developed three different protein arrays to measure IgG autoantibodies associated with Connective Tissue Diseases (CTDs), Anti-Cytokine Antibodies (ACA), and anti-viral antibody responses in 147 hospitalized COVID-19 patients in three different centers.

Project description:To identify cytokines secreted by pancreatic cancer cells, we compared the cytokine profiles of conditioned medium from pancreatic cancer cell Su.86.86 treated with or without JAG1 siRNA, using a Human Antibody Arrays 507 (L-507, Raybiotech)
Project description:we evaluated cytokine profiling of bone marrow serum samples in AML patients and healthy controls. Protein expression profiling of serum from 9 AML patients and 5 healthy controls was obtained using biotinylated antibody chip. Total 507 cytokines and growth factors were analyzed. Compared with healthy people, AML patients expressed 31 signature proteins, among which, 27 were found significantly higher expressed and 4 proteins were lower.
Project description:Protein and phosphorylation (Phospho Explorer Antibody Array, FullMoonBioscience, #PEX100) profiling of peritoneal monocytes (pooled lavages from 3-4 mice / condition) was carried out according to the manufacturer’s instructions.
Project description:8 controls and 26 RA samples were profiled using NimbleTherapeutics high density peptide array. Array consists of >4.6M peptides, includes citrullination and homocitrullination against the entire human proteome represented as overlapping 16mer peptides.
Project description:In search for peptides with higher or special binding affinity and for further understanding of the mode of action, a full substitutional analysis of peptide PeB using microarrays was performed. Thus, 152 PeB mutant variants were generated. In each of them, the full-length sequence was preserved except for only one amino acid from the eight loop-forming amino acids of the original PeB peptide (ARDFYDYDVFYYAMD) which was substituted with the 19 remaining natural amino acids. To assess binding, influenza material was labeled with a protein reacting fluorophore.
