Application
Biocytin is used as a substrate to study the specificity and kinetics of biotinidase(s), to measure biotinidase deficiency and as a model compound to study various uptake mechanisms of cells and tissues. Biocytin has been used to label neurons, medium spiny neurons and optic nerves.
Biochem/physiol Actions
Biocytin is an adduct of lysine and biotin. It is hydrolyzed by biotinidase, which acts on peptide-incorporated biotin or free biotin. Biocytin acts as a coenzyme.

Purpose: Radionuclide therapy directed against tumors that express somatostatin receptors (SSTRs) has proven effective for the treatment of advanced, low- to intermediate-grade neuroendocrine tumors in the clinic. In clinical usage, somatostatin peptide-based analogs, labeled with therapeutic radionuclides, provide an overall

Cerebrocortical injuries such as stroke are a major source of disability. Maladaptive consequences can result from post-injury local reorganization of cortical circuits. For example, epilepsy is a common sequela of cortical stroke, but the mechanisms responsible for seizures following cortical

Dendritic spines in the developing mammalian neocortex are initially overproduced and then eliminated during adolescence to achieve appropriate levels of excitation in mature networks. We show here that the L1 family cell adhesion molecule Close Homolog of L1 (CHL1) and
