Rhod-2 AM (solution)
Based on 1 Customer Validation
Rhod-2 (solution) is a high-affinity visible light excitation wavelength Ca2+ fluorescent probe, Rhod-2, AM is an acetyl methyl ester derivative of Rhod-2, which has cell membrane permeability and can easily enter cells with simple culture. Once it enters the cell, it is sheared by its lactesterase to produce Rhod-2 without membrane permeability, which remains in the cell to perform the corresponding physiological functions. Maximum excitation/emission wavelength: 549/578 nm.

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
1. Preparation of Rhod-2 AM working solution
Dilute the stock solution in serum-free cell culture medium or PBS. The corresponding stock solution can be diluted according to the actual situation. Note that if the solvent is DMSO, the cytotoxicity of DMSO must be considered, and a solvent control should be prepared; if the solvent is pure water, the working solution needs to be filtered and sterilized before adding cells.
Note: Please adjust the concentration of Rhod-2 AM working solution according to the actual situation.
2. Cell staining (Suspension cells)
2.1 Centrifuge at 1000 g at 4°C for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time. The cell density is 1×106/mL.
2.2 Add 1 mL of working solution, and then incubate at room temperature for 5-30 minutes.
2.3 Centrifuge at 400 g at 4°C for 3-4 minutes and then discard the supernatant.
2.4 Wash twice with PBS, 5 minutes each time.
2.5 Resuspend cells with serum-free cell culture medium or PBS. Observation by fluorescence microscopy or flow cytometry.
3. Cell staining (Adherent cells)
3.1 Culture adherent cells on sterile coverslips.
3.2 Remove the coverslip from the medium and aspirate excess medium.
3.3 Add 100 μL of working solution, gently shake it to completely cover the cells, and then incubate at room temperature for 5-30 minutes.
3.4 Wash twice with medium, 5 minutes each time. Observation by fluorescence microscopy or flow cytometry.

Transepithelial/transendothelial electrical resistance assay
TEER measures electrical resistance across epithelial or endothelial monolayers cultured on permeable supports, and the readout reflects ionic conductance through the cell barrier, especially the paracellular pathway regulated by junctional integrity. TEER can be measured without destroying the monolayer and is commonly used before or during transport, permeability, barrier-disruption, and barrier-maturation experiments. TEER values are influenced by biological maturation and technical conditions; reported factors include temperature, medium formulation, passage number, electrode geometry, membrane properties, and junctional length during early monolayer maturation. Therefore, TEER should be interpreted with blank-insert subtraction, area normalization, repeated readings, and, when possible, orthogonal barrier readouts such as FITC-dextran flux or tight-junction staining.

Ca2+ Staining Technique
Ca2+ staining is an experimental technique that utilizes specific fluorescent probes (such as Fluo-4 AM, Fura-2, etc.) to qualitatively or quantitatively detect dynamic changes in intracellular Ca2+ concentrations; this is achieved by monitoring the changes in fluorescent signals generated when these probes bind to free intracellular calcium ions. The underlying principle relies primarily on the presence of chelating groups within the probe's molecular structure that possess high affinity for calcium ions.
