When it comes to reliable protein reduction, TCEP (Tris(2-carboxyethyl)phosphine) stands out as a clear favorite among biochemists and life science researchers. At Soltec Ventures, we supply high-purity TCEP designed for consistent performance, minimal odor, and superior stability — ensuring your experiments deliver reproducible, dependable results every time.
What Is TCEP?
TCEP is a powerful, odorless reducing agent that selectively breaks disulfide bonds in proteins and peptides. Unlike older reagents such as DTT or β-mercaptoethanol, TCEP offers a non-thiol alternative that's stable in aqueous solution and remains active over a broad pH range (1.5–8.5).
That means you get all the reduction power you need — without the volatility, odor, or oxidation issues that plague other reagents.
Why Researchers Choose Soltec Ventures TCEP
At Soltec Ventures, we understand that research doesn't just demand performance — it demands reliability and traceability. Our TCEP reagents are manufactured to exacting standards, providing:
- High purity and low odor – for a cleaner lab environment and consistent results.
- Superior stability – remains active longer in aqueous solutions and at room temperature.
- Compatibility – ideal for protein and peptide reduction, crosslinking workflows, mass spectrometry prep, and electrophoresis applications.
- Traceable lots and technical support – each batch includes documentation and support for regulated environments.
Our customers use Soltec Ventures TCEP in diverse workflows — from protein folding studies and enzymatic assays to sample prep for LC-MS/MS and Western blotting.
Advantages of TCEP Over DTT and β-Mercaptoethanol
| Property | TCEP | DTT | β-Mercaptoethanol |
|---|---|---|---|
| Odor | Odorless | Mild sulfur odor | Strong, unpleasant odor |
| Stability | Highly stable | Easily oxidized | Easily oxidized |
| pH Range | 1.5–8.5 | 6.5–9.0 | 7.0–9.0 |
| Thiol Interference | None | Thiol-based | Thiol-based |
| Metal Chelation | Minimal | Moderate | High |
With TCEP, you gain a cleaner, more stable reduction that doesn't interfere with downstream assays — perfect for mass spec workflows and sensitive analytical methods.
Applications
TCEP from Soltec Ventures can be used across a wide range of biochemical applications:
- Reduction of disulfide bonds in proteins and peptides
- Preparation of samples for SDS-PAGE or 2D electrophoresis
