Phosphate buffered saline with gelatin and 0.1% sodium azide.
Preparation And Storage
The FITC and PE conjugates are each supplied in 1.0 mL of PBS containing gelatin and 0.1% sodium azide. Please refer to the vial label for antibody concentration. The vial should be stored at 2° to 8°C. Conjugated forms should not be frozen and should be protected from prolonged exposure to light. Each reagent is stable for the period shown on the bottle label when stored as directed.
The AS10 antibody reacts with human interleukin-1β (IL-1β) which is also known as endogenous pyrogen (EP), leukocyte endogenous mediator (LEM), mononuclear cell factor (MCF) and lymphocyte-activating factor (LAF). IL-1β is a proinflammatory cytokine that is synthesized as a precursor of 31 kDa and is converted intracellularly to the mature 17.5 kDa form, after cleavage by the IL-1β-converting enzyme (ICE). In healthy individuals, IL-1β is secreted non-constitutively by blood monocytes, tissue macrophages and dendritic cells. IL-1β is also constitutively expressed in the human hypothalamus. Many malignant tumors express IL-1β as part of their neoplastic nature. The AS10 antibody has been reported not to recognize human IL-1α nor cross react with mouse IL-1β.

R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
