Spurr low viscosity embedding kit, Sigma-Aldrich®
Supplier: SIGMA ALDRICH MICROSCOPY
Spurr resin is a hydrophobic resin. It is less viscous than epon mixtures and is easier to dispense. The low viscosity of the resin contributes to its penetration in tissue, mineral and dense structures. A low viscosity of 60 cps also allows easy penetration into a variety of difficult materials.

Fura 2-AM ≥95% (by HPLC)
Supplier: SIGMA ALDRICH MICROSCOPY
Fura 2-AM (Fura 2) is a calcium-specific ratio-metric fluorescent dye. It is also known as acetoxy-methyl-ester. In response to calcium ions, ratio metric dyes like Fura 2 changes their respective excitation or emission spectra. The intracellular calcium concentration is determined by the fluorescence emission ratio or excitation at distinct wavelengths. Fura 2 has an emission peak at 505 nm, and the excitation peak ranges between 340 to 380 nm and is the preferred calcium indicator.
