Flow cytometric analysis of somatostatin expression in human somatostatin-transfected 293F cells. Untransfected (dashed-line histogram) and human somatostatin-transfected (solid-line histogram) 293F cells were fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655) and permeabilized with BD Phosflow™ Perm Buffer III (Cat. No. 558050). The cells were washed and stained with Alexa Fluor® 488 Mouse Anti-Human Somatostatin (Cat. No. 566032).The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of intact cells. Flow cytometry was performed on a BD FACSCanto™ II flow cytometry system.
Immunohistofluorescent staining of somatostatin in human islets of Langerhans. Following antigen retrieval with BD Pharmingen™ Retrievagen A Buffer (Cat. No. 550524), sections of formalin-fixed, paraffin-embedded human pancreas were blocked using an Avidin/Biotin Blocking Kit (Vector Laboratories, Cat. No. SP-2001) as recommended by the manufacturer. LEFT PANEL: The section was stained with Alexa Fluor® 488 Mouse Anti-Human Somatostatin (Cat. No. 566032, pseudocolored red), and cell nuclei were counterstained with BD Pharmingen™ DAPI Solution (Cat. No. 564907, pseudo-colored green). RIGHT PANEL: The section was stained with Alexa Fluor® 488 Mouse Anti-Human Somatostatin (Cat. No. 566032, pseudocolored red), BD Horizon™ BV421 Mouse Anti-Glucagon (Cat. No. 565891, pseudocolored blue), and Alexa Fluor® 647 Mouse Anti-Insulin (Cat. No.565689, pseudocolored green). The photographs were performed on a standard epifluorescence microscope. Original magnification, 20x.

Preparation And Storage
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to Alexa Fluor® 488 under optimum conditions, and unreacted Alexa Fluor® 488 was removed.
Product Notices
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.

- The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
- Alexa Fluor® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).

Antibody Details
U24-354
Somatostatin is produced by neuroendocrine neurons in the hypothalamus and δ cells in the islets of Langerhans of the pancreas. It is a regulatory hormone that affects neurotransmission, cell proliferation, and numerous hormones of the endocrine system. Via interaction with high affinity G protein-coupled somatostatin receptors, it inhibits the secretion of somatotropin (also known as growth hormone or GH), thyroid-stimulating hormone (thyrotropin or TSH), and most gastrointestinal and pancreatic hormones, including glucagon and insulin. The expression of somatostatin can be used to monitor the pancreatic differentiation of pluripotent stem cells.
The human somatostatin gene, SST, encodes the precursor molecule preprosomatostatin (amino acids 1-116), which is cleaved to form prosomatostatin (amino acids 15-116), which in turn is cleaved to form either of 2 alternative active somatostatin peptides, somatostatin-28 (amino acids 89-116) or somatostatin-14 (amino acids 103-116). The U16-850 monoclonal antibody detects human preprosomatostatin in somatostatin-producing cells.

Format Details
Alexa Fluor™ 488
Alexa Fluor™ 488 Dye is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 517-nm. Alexa Fluor™ 488 is designed to be excited by the Blue laser (488 nm) and detected using an optical filter centered near 520-nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
