NEW STEROID HAPTENS FOR RADIOIMMUNOASSAY - SYNTHESIS OF STEROIDS SUBSTITUTED WITH THIOETHER OR ESTER LINKAGES AT THE 2-ALPHA-POSITION

open access: yes, 1991
Haptens with bridge at the 2-position have not yet been explored. Radioimmunoassays with antibodies directed against 2-alpha-alkyl bridged steroid haptens are expected to be highly specific due to greater topographical exposure and similarity in ...

Recent Advances in Food Allergens and Emerging Biosensing Technologies

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Food allergies have become a worldwide public health issue, highlighting the critical need for rapid, sensitive, and field‐deployable detection strategies. While traditional detection methods offer high accuracy, their high cost, operational complexity, and lengthy analysis time limit their applicability for rapid screening purposes.

Synthesis and identification of artificial antigen for chloramphenicol

open access: yes浙江大学学报. 农业与生命科学版, 2006
In order to establish the immunoassay method of chloramphenicol (CAP), two haptens (CAP-HS1, CAP-HS2) were synthesized by chloramphenicol and succinic anhydride and identified by ESI-MS. The haptens were conjugated to bovine serum albumin (BSA), with the

T cell receptor (TCR) interaction with haptens: metal ions as non-classical haptens

open access: yes, 2005
Haptens are classified as low molecular chemicals with an intrinsic potential to covalently modify proteins, and many of them are strong inducers of contact hypersensitivity (CHS).

Developmental Fates of Progenitor/Undifferentiated Cells With Histone Trimethylation Tags in the Stony Coral, Acropora tenuis

open access: yesDevelopment, Growth &Differentiation, Volume 68, Issue 7, September 2026.
In the stony coral, Acropora tenuis, embryos and larvae have progenitor/undifferentiated cells. Undifferentiated‐like cells differentiate into the pharyngeal stomodeum at an early larval stage, and nerve progenitors possess the dual potential to differentiate into nerve cells and vacuolated hyaline cells, depending on the oral‐aboral position ...
