Lysis buffers are solutions used to break open cells, allowing researchers to extract proteins, nucleic acids, and other cellular components. They make sure these components are released effectively while preserving their integrity for downstream applications, such as western blotting.

We offer a wide range of lysis buffers designed for molecular biology, biochemistry, and proteomic assays. Each formulation is tested to deliver consistent results, so you can focus on your research without worrying about variability.

Composition and types

General lysis buffers

These buffers work for extracting a broad range of proteins from cells and tissues. They often contain non-ionic detergents that solubilize membrane proteins and disrupt cellular structures without damaging protein function.

Nuclear and subcellular lysis buffers

When you need proteins from specific compartments, such as the nucleus or mitochondria, these buffers help isolate them cleanly. They’re essential for studying compartmentalized processes such as transcription or energy metabolism.

Specialized lysis buffers

Some buffers are tailored for unique cell types, like red blood cells, or for specific downstream applications. These formulations save time and improve accuracy when working with challenging samples.

Features and benefits

Optimized formulations

Our buffers are designed to maximize yield and maintain protein integrity, so your experiments start with the best possible material.

Compatibility

They work seamlessly with common techniques like western blot, ELISA, and immunoprecipitation (IP). That means fewer adjustments and more reliable results.

Quality tested

Every batch undergoes rigorous testing to ensure performance. You can trust that what’s in the bottle will deliver consistent outcomes.

Applications and use cases

Protein extraction for western blotting

Western blotting starts with clean protein samples. Our lysis buffers help release proteins in a form suitable for SDS-PAGE separation and antibody detection. For example, RIPA buffer is widely used because it extracts both cytoplasmic and membrane proteins efficiently.

Nucleic acid preparation for PCR

High-quality DNA and RNA are critical for PCR. Specialized buffers minimize degradation and contamination, giving you reliable amplification results. Many researchers use buffers with chaotropic agents for RNA isolation to protect against RNases.

Subcellular analysis

Studying organelles like mitochondria or nuclei requires precision. Compartment-specific buffers preserve these structures during extraction, enabling accurate downstream analysis such as proteomics or imaging.

Protocol flexibility

Our buffers fit into standard workflows but also adapt to custom protocols. Whether you’re scaling up for high-throughput screening or working with rare samples, you can count on consistent performance.

Advanced applications

Researchers exploring protein-protein interactions often pair lysis buffers with crosslinking agents before immunoprecipitation. Others use them in chromatin immunoprecipitation (ChIP) to study DNA-protein complexes. These advanced techniques rely on buffers that maintain structural integrity while allowing selective extraction.

Lysis buffer selection guide

Selecting the right lysis buffer is key to efficient protein extraction and reliable downstream results. The optimal choice depends on your sample type and the location of your target protein.

Use the guide below to identify a suitable buffer for your application.

Common lysis buffer types

There are several commonly used lysis buffers, each designed for different levels of cell disruption and downstream applications.

RIPA buffer is a strong, widely used lysis buffer suitable for extracting cytoplasmic, nuclear, and membrane proteins, making it a popular choice for western blotting.

NP-40 and Triton X-100 buffers are milder, non-denaturing options that preserve protein structure and interactions, often used for cytoplasmic protein extraction and immunoprecipitation workflows.

IP lysis buffers are specifically formulated for immunoprecipitation, helping to maintain protein-protein interactions while enabling efficient extraction.

Selecting the right buffer depends on the balance between extraction strength and preserving protein integrity for your downstream application.

Explore all our lysis buffers

Lysis buffers are often used alongside other reagents to support efficient protein extraction and analysis. For example, protease inhibitors are commonly added during cell lysis to prevent protein degradation, while western blot reagents and sample preparation kits are used in downstream applications to analyse extracted proteins.

For immunoprecipitation workflows, specialised IP lysis buffers and kits can help preserve protein-protein interactions and improve pull-down efficiency. Exploring compatible reagents and protocols alongside your chosen lysis buffer can help ensure reliable and reproducible results.

Lysis buffer protocols and related products

Using the correct protocol is essential for effective cell lysis and optimal protein recovery. Factors such as incubation time, temperature, and method of disruption can impact your results.
