The summaries below describe peer-reviewed literature for educational and reference purposes only. They do not describe uses of this product, which is sold for laboratory research only.
Induction of pituitary cell type differentiation by delta sleep-inducing peptide
Authors: A G Héritier, O Stettler, P M Dubois
Source: https://pubmed.ncbi.nlm.nih.gov/8022523/
Pituitary primordia from 11-day-old rat fetuses were cultured with DSIP, GnRH or TRH, and immunocytochemistry was used to quantify differentiation of LH, TSH, prolactin, GH and ACTH cell types. DSIP induced LH and TSH cell differentiation in a concentration-dependent manner.
In-vitro characterization of blood-brain barrier permeability to delta sleep-inducing peptide
Authors: S Raeissi, K L Audus
Source: https://pubmed.ncbi.nlm.nih.gov/2576448/
Using primary brain microvessel endothelial cell monolayers in a side-by-side diffusion apparatus with HPLC-UV detection, researchers measured DSIP flux, which was linear, non-saturable, bidirectional and insensitive to temperature and metabolic inhibitors.
Human pheochromocytoma cells studied in culture contain large amounts of DSIP-like material
Authors: Ola Nilsson, Bo Wängberg, Anneli Wigander, Kerstin Lundmark, Annica Dahlström, Håkan Ahlman, Anders Bjartell, Rolf Ekman
Source: https://www.sciencedirect.com/science/article/pii/019697819190063U
Immunocytochemistry and immunogold electron microscopy detected DSIP-like immunoreactive material in secretory granules of cells from nine human pheochromocytoma tumors, and HPLC of conditioned culture media indicated its release from cultured cells.
Storage and handling
DSIP is supplied for laboratory use. Store unopened vials cold and protected from light, and follow the storage notes on the vial label. Handle only in an appropriate laboratory setting by qualified personnel.
