ADME
ADME Research Domain
Metabolism; Absorption; Excretion
Description
Located on the luminal side of renal tubular epithelial cells, this cell line is specifically designed to simulate drug uptake or reabsorption from the urine side. It performs exceptionally well in assessing diuretic interactions and the balance of certain steroid sulfates.
Features
1. Unique anion exchange functional validation supporting both forward and reverse transport studies. 2. Assay window optimized specifically for the renal excretion environment. 3. Maintains consistent polar distribution of transport proteins over long-term passages.
Applications
Predicting diuretic accumulation in kidneys and DDI risks; Studying the renal retrieval process of progestogen metabolites.

Background
OAT4 (SLC22A11) is uniquely localized to the apical (luminal) membrane of renal proximal tubules and the placenta. Unlike basolateral OATs, OAT4 acts as an asymmetrical exchanger, contributing to the reabsorption of estrone sulfate and uric acid from the urine, while mediating the active secretion of certain drug conjugates.

Sterility Testing
Creative Biolabs provides sterility testing in accordance with USP and EP regulations. All of our sterility testing is performed in an isolator or clean room environments. The cell line has been screened using the membrane filtration testing methods to confirm the absence of aerobic, anaerobic and fungi microorganisms.
Identity Testing
Identity testing is required for newly established cell lines. Isoenzyme analysis is used to confirm the identity of the species of a cell line. Alternative methods for identity testing include DNA fingerprinting, STR analysis and karyology.
Virological Safety Testing
A broad range of viruses is susceptible to affecting human cell lines. We can provide in vivo/vitro virus saftey assays by utilizing various animal systems. These viruses include: adventitious viruses, bovine viruses, human and simian viruses, porcine viruses, retrovirus and rodent viruses.
Genetic Stability Testing
We perform cell genetic stability studies under ICH guidelines. We can provide guidance on the appropriate testing program upon your requirements.
Mycoplasma Testing
The cell line has been screened using the luciferase based mycoplasma detection kit to confirm the absence of mycoplasma species.
Shipping
Dry Ice
Storage
Frozen cells should be stored in a liquid nitrogen tank (-150°C~-190°C). Once reconstituted, the cells may be used for up to five days if properly stored at 2°C - 8°C in the buffer provided.
Handling Notes
Frozen cells should be thawed immediately upon receipt and grown according to handling procedure to ensure cell viability and proper assay performance.
Note: Do not freeze the cells upon receipt as it may result in irreversible damage to the cell line.
Disclaimer: We cannot guarantee cell viability if the cells are not thawed immediately upon receipt and grown according to handling procedure.
Warnings
Avoid multiple freeze/thaw cycles
