Calcein (solution)
Based on 1 Customer Validation
Calcein (solution) (Fluorexon (solution)) is a fluorescent dye and self-quenching probe, used as an indicator of lipid vesicle leakage, and also as a complexometric indicator for titration of calcium ions with EDTA, and for fluorometric determination of calcium. Calcein cannot directly cross the intact cell membrane of a living cell, unlike Calcein-AM (HY-D0041) which is cell-permeable. Calcein can also be used as a model drug for evaluating efficiency and bioavailability of drug delivery systems.

体外実験
Description: Calcein is a fluorescent probe with yellow green fluorescence, it can be used to determine labile iron pool and measure the Fe(III)-binding affinity with ligands[3].
Guide (The following is our recommended protocol. This protocol is only a guide and should be modified according to your specific needs).
1. Solution preparation[3]
1.1 Preparation of working solution
Dilute to 0.5 μM with PBS or cell culture medium.
Note: The working solution should be prepared and used immediately. Keep it away from light.
2. Cell staining
2.1 Cells (106/mL) are loaded by incubation with 20 μM Fe(II) for 2 h at 37°C.
2.2 Cells are collected by centrifugation (1000 rpm; 5 min) and Calcein (0.5 μM) is directly injected into the cells via microinjection for staining (5-15 mins).
2.3 Wash cells for twice by D’hanks buffer (pH 7.4).
2.4 The fluorescence is monitored by both flow cytometry and a confocal laser scanning microscope.

Protocol for Pharmacokinetic Study
Pharmacokinetic studies quantify how an organism handles a drug over time through absorption, distribution, metabolism, and excretion, and the core experimental readout is the concentration-time profile of parent drug and, when relevant, metabolites in biological matrices such as plasma, whole blood, urine, bile, or tissue. Pharmacokinetic analysis links dose, route, exposure, clearance, half-life, distribution, bioavailability, and systemic exposure to drug efficacy and toxicity hypotheses rather than measuring a signaling pathway directly. The literature links pharmacokinetics to drug-development phenotypes by showing that drug metabolism and pharmacokinetics influence compound progression, exposure-response interpretation, safety margins, dosing strategy, and failure risk during discovery and development. DMPK science contributes to compound optimization by integrating physicochemical properties, in vitro metabolism, transporter behavior, in vivo exposure, and pharmacodynamic contex
