| In Vitro | Lumogallion (1 mM, 45 min) can be used to detect aluminum levels in brain tissue of Alzheimer's patients[1]. Lumogallion can be used as a probe to stain live cells with intracellular aluminum adjuvant[2]. Lumogallion (10 μM, 60 min) can be used to detect aluminum content in root tip cell tissue of plants[3]. Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs). 1. Dissolved lumogallion in 0.1 M acetate buffer (pH 5.2). 2. Sample and 10 μM lumogallion were co-incubated for 60 min in the dark. 3. Washed the mixed sample well with acetate buffer solution twice, 15 minutes each, and observed under a confocal laser microscope. 4. Excitation wavelength is 488 nm , emission wavelength is 520 nm. |
