Description
The proximal tubule is the nephron segment that does the reabsorption and takes most of the drug-induced injury, and it is the renal model almost every buyer actually wants. It is also the clearest example on this site of a category where the cells are cheap and public and the finished model is not purchasable at all. Two suppliers publish live list prices for human renal proximal tubular epithelial cells, and both let the buyer pick an age grade, which matters because fetal, neonatal and adult tubular cells differ in transporter expression. What no supplier surveyed sells is a released, barrier-verified proximal tubule model with a stated TEER or transporter acceptance criterion. MIMETAS lists Kidney among its OrganoPlate organ models and sells OrganoReady as perfused ready-to-use tissue prepared by its own staff at 40 or 64 tissue models per plate with all reagents and medium included, but the OrganoReady range published on its page covers colon organoid, colon Caco-2, collagen, BBB HBMEC, blood vessel HUVEC and angiogenesis HUVEC, a renal OrganoReady is not among them, so the kidney route on that platform is an empty plate you seed. CN Bio's Multi-chip Barrier plate is a general barrier consumable rather than a kidney product. Newcells Biotech is the named specialist with a proximal tubule line, and it is the one supplier in this category we could not verify: automated retrieval of its site failed on every attempt across our coverage, and a direct fetch on the build date failed with a TLS certificate validation error, so nothing about its products, prices or willingness to supply is asserted here. The honest position is that this is an assembly job: buy publicly priced cells, buy a publicly priced perfused or insert consumable, and contract the seeding, differentiation and barrier verification.
Why this is hard to buy today
Renal proximal tubular epithelial cells have a live list price at two suppliers and a perfused culture plate has a live list price at a third, but no party will sell the assembled tubule against a barrier or transporter acceptance criterion, so the buyer pays for the parts and personally absorbs the risk that the epithelium never polarises or never expresses the transporter the study depends on. The one named specialist in the category cannot be evaluated at all: its site has blocked every automated retrieval attempt we have made and failed TLS certificate validation on the build date.
Price evidence
No supplier surveyed sells a finished, barrier-verified human proximal tubule model at a published price, and no quote-gated supplier in this category publishes an indicative figure. This offering is therefore quote only and the item itself is unpriced. What is verified are the input components, which is what makes a quote checkable. Cells, live vendor store APIs observed 2026-09-01: iXCells Human Renal Proximal Tubular Epithelial Cells, catalogue 10HU-112, $771.00; Cell Applications Human Renal Proximal Tubular Epithelial Cells HRPTEpC, price range $864.00 to $1,174.00 across age grade and format (adult 930-05a, fetal 930-05f, neonatal 930-05n, with matched total kits at the 930K prefix); Cell Applications Human Renal Glomerular Epithelial Cells HRGEpC $893.00. Perfused consumables, AIM Biotech live store API observed 2026-09-01: idenTx 40 Plate, catalogue IDTX40, box of 5 plates at 40 chips per plate, $2,220.00, which is $444.00 per plate and $11.10 per chip; idenTx 9 Plate IDTX9, box of 8, $690.00; organiX Plate OGNXP-1EA $410.00. Those are prices for a general microfluidic culture plate, not for a kidney model. MIMETAS publishes no price for OrganoPlate or OrganoReady and states 'Discuss your needs'. Newcells Biotech is explicitly unpriced and unverified: the site blocked automated retrieval across repeated attempts in our supplier coverage and a direct fetch on 2026-09-01 failed with a TLS certificate validation error.
These are supplier list prices we located and recorded, not a quotation from Wetware World. Your price depends on quantity, specification and freight, and is only binding once issued in writing.
What you must specify
A quote cannot be produced without these. Anything you leave open, a supplier will assume, usually expensively.
| # | Parameter |
|---|---|
| 01 | Geometry: perfusable tubule in a microfluidic lane versus flat epithelium on a permeable insert |
| 02 | Cell source and age grade (adult, neonatal, fetal), which changes transporter expression |
| 03 | Primary cells versus an immortalised or iPSC-derived source |
| 04 | Whether an endothelial or interstitial compartment is required alongside the tubular epithelium |
| 05 | Named transporters that must be functionally demonstrated, not merely expressed |
| 06 | Barrier acceptance criterion (TEER or permeability coefficient) and the method used to measure it |
| 07 | Flow regime and shear stress, if a perfused configuration is specified |
| 08 | Number of tubules or chips and the replicate structure |
| 09 | Whether the buyer already owns a platform the model must run on |
Quality documentation
Typically available with this item. What actually ships is confirmed on the quotation, per supplier.
- Supplier certificate of analysis for each cell input
- Barrier integrity measurement at release (to be negotiated into the contract, not assumed)
- Transporter expression or functional transport evidence, specified explicitly
- Morphology and polarisation by imaging
- Sterility and mycoplasma per supplier release testing
