Variation in size and location of the Ag-NOR in the Atlantic halibut (Hippoglossus hippoglossus)
, 2008 The distribution of differentially stained chromatin was studied in the Atlantic halibut (Hippoglossus hippoglossus) chromosomes (2n = 48). Four pairs of homologous chromosomes were identified using a combination of traditional cytogenetic staining ...

An experimental approach to the study of ag-nor proteins [PDF]
, 1994 Purified polyclonal antibodies have been obtained against 100 KD and 36 KD Ag-NOR proteins. These two antibodies have been used to study the immunolocalization of both proteins on different cell types subjected to various conditions of cell activity ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation
FEBS Letters, EarlyView.Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.
