A New Type of Modified Brassinosteroids for Enzyme-linked Immunosorbent Assay

Natural Product Communications, 2008
New modified brassinosteroids (BS) with a full set of specific functional groups and with an additional one at C-26 have been synthesized and used as haptens for enzyme-linked immunosorbent assay. The haptens were conjugated to bovine serum albumin (BSA)

Immunochemical studies of organ and tumor lipids. XIX. Cytolytic action of antibodies directed against cytolipin R

Journal of Lipid Research, 1972
Rabbit antisera to rat lymphosarcoma contain antibodies that are cytolytic for rat erythrocytes in the presence of complement. The reaction can be inhibited completely by pure cytolipin R showing that (a) immune hemolysis can be mediated through lipid ...

Hapten designs based on aldicarb for the development of a colloidal gold immunochromatographic quantitative test strip

Frontiers in Nutrition, 2022
The common carbamate insecticide aldicarb is considered one of the most acutely toxic pesticides. Herein, rational design was used to synthesize two haptens with spacers of different carbon chain lengths. The haptens were then used to immunize mice.

Extrinsic Cotton Effects in Hapten—Carrier and Hapten—Antibody Interactions [PDF]

Proceedings of the National Academy of Sciences, 1971
Two homogeneous univalent hapten-protein conjugates, prepared by the covalent attachment of a single 2,4-dinitrophenyl (DNP-) or 2,4,6-trinitrophenyl (TNP-) side chain to the cysteine-SH in the active site of the enzyme papain, have been found to exhibit large Cotton effects in the wavelength region of the absorption bands of the DNP or TNP groups ...

HaptenDB: a comprehensive database of haptens, carrier proteins and anti-hapten antibodies [PDF]

, 2006
The key requirement for successful immunochemical assay is the availability of antibodies with high specificity and desired affinity. Small molecules, when used as haptens, are not immunogenic.

Skin Sensitisation and Dermatitis Among Epoxy-Exposed Workers in a Wind Turbine Plant: Influence of Occupational Factors. [PDF]

Contact Dermatitis
Epoxy resin sensitisation remains a relevant occupational risk in wind turbine blade manufacturing, confined to high‐exposure tasks and often presenting as hand dermatitis. Accurate diagnosis requires epoxy‐specific patch testing, and prevention must go beyond personal protective equipment.

RORγt‐APCs: The New Masters of Oral Tolerance

Barrier Immunity, EarlyView.
ABSTRACT Oral tolerance is defined by the hypo‐responsiveness of our body to fed antigens, and its failure can lead to immune‐mediated diseases, such as allergy, chronic inflammation and autoimmune diseases. Decades of research have demonstrated that antigen‐presenting cells (APCs) promote oral tolerance by inducing regulatory T cells (Tregs) and/or ...

Genetically Engineered Nanobody–Recombinant Antibody Colloidal Gold Strip for Ultrasensitive Atrazine Detection in Fruits and Vegetables

Food Safety and Health, EarlyView.
A sensitive colloidal gold immunochromatographic assay for atrazine was successfully established using genetically engineered nanobody‐recombinant antibody, which overcame the shortcomings of traditional antigen‐antibody. ABSTRACT Colloidal gold immunochromatography (CG‐ICA) is distinguished by its cost‐effectiveness and rapid detection capabilities ...
