Regulatory Status Legend
The T56-706 monoclonal antibody specifically binds to insulin, a member of the insulin family of active peptides. Insulin is an evolutionarily conserved peptide hormone that binds to receptors on target cells (primarily adipose and muscle) to promote the absorption of glucose from the blood, thus regulating fat and carbohydrate metabolism. Insulin is produced by β cells in the islets of Langerhans of the pancreas. There, the precursor molecule, preproinsulin, is cleaved to proinsulin that is in turn cleaved to form the mature insulin hormone, which is composed of two peptides (A- and B-chains) linked by 2 disulfide bonds. Mature insulin is stored in granules in the β cells and is released to the blood in response to metabolic signals such as glucose, the amino acids arginine and leucine, and acetylcholine. Catecholamines can regulate blood glucose levels by either stimulating or inhibiting the release of insulin from β cells. The expression of insulin can be used to monitor the pancreatic differentiation of pluripotent stem cells.
Alexa Fluor® 647 conjugates are highly photostable and remain fluorescent over a broad pH range. The excitation and emission maxima are nearly identical to those of APC. However, APC tends to be brighter while Alexa Fluor® 647 is more optimal for intracellular applications. This fluorochrome exhibits uncommon photostability, making it an ideal choice for use in fluorescence microscopy. Due to nearly identical excitation and emission properties but different spillover characteristics, APC and Alexa Fluor® 647 cannot be used simultaneously.

Preparation and Storage
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
