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.

Fluorescein (FITC) 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 518-nm. FITC 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.
