Metabolism; Absorption; Excretion
Description
Distinct from liver-exclusive isoforms, our Vesitra™ Human OATP2B1 is specially acclimated to tolerate mildly acidic assay buffers (pH 5.5-6.0). This mirrors the physiological pH in the intestinal microenvironment, providing highly relevant data for predicting oral drug absorption.
Features
1. pH-sensitive optimization offering a stable assay window under both acidic intestinal and neutral blood conditions. 2. Minimized background noise achieved via gene editing of endogenous HEK293 uptake proteins.
Applications
Investigating intestinal absorption mechanisms of oral solid dosage forms; in vitro simulation of food-drug interactions (e.g., grapefruit juice effects).

Background
OATP2B1 (SLCO2B1) exhibits a broader tissue distribution than the liver-specific OATPs, with significant expression in the liver, intestine, kidney, and blood-brain barrier (BBB). In the intestine, it facilitates the absorption of certain orally administered drugs, making it an important target for understanding complex absorption profiles and potential food-drug or drug-drug interactions.

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
