Family Snapshot

Five formulations on one Tris platform

Tris-based buffers provide an effective and versatile option for protein extraction and lysis, with the specific formulation depending on the experimental needs and protein characteristics. Their ability to maintain physiological pH and compatibility with various additives make them a popular choice in molecular biology and biochemistry research.

  • Nine products, fourteen catalog entries. Five base lysis/extraction buffers across ten sizes, plus four ready-to-use protease inhibitor cocktail pre-blends.
  • Five distinct formulations: Nonidet-P40 (NP-40) Buffer, Tris NP-40 Buffer, RIPA Buffer, Cytoskeleton Extraction Buffer, and Tris Triton-X Buffer.
  • One product carries a stated special attribute: Nonidet-P40 (NP-40) Buffer contains glycerol.
  • Supplied as a clear, colorless liquid and stored at 4 °C.
  • Quadruple-stage filtration: filtered 0.1 micron twice and 0.04 micron twice, in a sterile environment.
  • Inhibitors are expected, not assumed. For protein extraction, protease inhibitors are often added to prevent proteolysis; enzyme inhibitors like phosphatase inhibitors may also be included for specific studies.
  • Seven inhibitor components in the pre-blends: AEBSF·HCl, Aprotinin, Bestatin, E-64, EDTA, Leupeptin, and Pepstatin A.

Why a Tris Base

Six reasons this family is the versatile default

Each card below is one property the source attributes to Tris-based lysis and extraction buffers.

tune

Effective and versatile

The source's own framing: Tris-based buffers are an effective and versatile option for protein extraction and lysis — which is why this family carries five formulations rather than one.

target

The formulation follows the target

The specific formulation depends on the experimental needs and the protein characteristics. That is a selection decision, not a default — NP-40, Triton-X, RIPA, and cytoskeleton extraction are different answers to different targets.

show_chart

Physiological pH

The ability to maintain physiological pH is one of the two properties the source names as making these buffers a popular choice in molecular biology and biochemistry research.

add_circle

Compatibility with additives

The second named property. It is what makes the pre-blended protease inhibitor versions in the second catalog band possible, and what lets you add your own inhibitors to the base buffers.

blur_on

Detergents open the cell

The method utilizes detergents to disrupt cell membranes and solubilize proteins. Across this family that means NP-40, Triton-X, the multi-detergent RIPA formulation, or the cytoskeleton extraction formulation.

shield

Inhibitors are part of the plan

For protein extraction, protease inhibitors are often added to prevent proteolysis, and enzyme inhibitors like phosphatase inhibitors may also be included for specific studies. The pre-blends ship that step already done.

Pick the formulation first, then decide who adds the inhibitors

The two catalog bands answer two different questions. The base band is where you choose the chemistry that matches your target. The pre-blend band is where you decide whether the seven-component cocktail arrives already combined with that buffer, or whether you add inhibitors yourself at the bench.

Filtration Architecture

Quadruple-stage filtration, in a sterile environment

The published sterility statement for this family is a four-pass membrane process: 0.1 micron twice, then 0.04 micron twice. A lysis buffer is added directly to the sample and travels with it downstream, so whatever the buffer carries becomes part of the lysate.

  1. 1

    0.1 µm Pre-filtration I

    First pass through a 0.1-micron membrane.

  2. 2

    0.04 µm Pre-filtration II

    First pass through a 0.04-micron membrane.

  3. 3

    0.1 µm Sterile-filtration I

    Second pass through a 0.1-micron membrane, performed in a sterile environment.

  4. 4

    0.04 µm Sterile-filtration II — Final Polish

    Final 0.04-micron polishing pass in a sterile environment. The buffer is delivered as a clear, colorless liquid.

Why the polish matters in a lysate

An ultra-filtered, ultra-low-particulate buffer keeps background out of colorimetric assays, gel electrophoresis, and quantitative immunodetection, and keeps it out of microfluidic and organ-on-a-chip (OoC) sample handling — where a particulate that would be invisible in a cuvette can block a channel.

Protease Inhibitor Cocktail

The seven components and what each one stops

These ready-to-use combinations of a protease inhibitor cocktail with various lysis buffers provide a powerful tool for efficient protein extraction while preserving protein integrity. This method utilizes detergents to disrupt cell membranes and solubilize proteins, while the carefully formulated protease inhibitor cocktail prevents protein degradation during the lysis process.

Component What it inhibits
AEBSF·HCl A serine protease inhibitor
Aprotinin Targets serine proteases and has anti-inflammatory properties
Bestatin An aminopeptidase inhibitor[4]
E-64 A cysteine protease inhibitor[2]
EDTA A metalloproteinase inhibitor
Leupeptin Inhibits both serine and cysteine proteases[5]
Pepstatin A An aspartic protease inhibitor[3]
One consequence of the EDTA in the cocktail. The source states that EDTA is present as a metalloproteinase inhibitor, and that it works by binding metal ions. That same chelation is not selective for proteases: any downstream step that depends on a metal-dependent enzyme, or on free divalent cations, sees the EDTA too. Worth checking against your workflow before the lysate goes forward. For a formulation question, contact support@diagnocine.com.

FAQ

Frequently asked questions

The questions that come up most often when choosing within this family.

The source gives two reasons: their ability to maintain physiological pH, and their compatibility with various additives. Together those make them a popular choice in molecular biology and biochemistry research, and an effective and versatile option for protein extraction and lysis.
Storage: 4 °C. Appearance: clear, colorless liquid. Sterility: filtered 0.1 micron twice and 0.04 micron twice, in a sterile environment. No pH figure is published for this family — the source describes physiological pH without giving a number, so none is stated here. Request lot documentation at support@diagnocine.com.
Through a quadruple-stage membrane process: 0.1 micron twice, then 0.04 micron twice, carried out in a sterile environment. Because a lysis buffer is added straight to the sample and stays with it through every downstream step, the polishing pass keeps particulate background out of the lysate itself. Filtration method and pass count can change per order.
The source states only that the specific formulation depends on the experimental needs and the protein characteristics — it publishes no comparison between the five, and none is invented here. What the catalog does tell you is which products share a chemistry: NP-40 covers three products, Triton-X two, RIPA two, and Cytoskeleton Extraction one. For help matching a formulation to a target, contact support@diagnocine.com.
The only difference the source states is in the Special column: Nonidet-P40 (NP-40) Buffer (DCP-NP401X) contains glycerol, and no special attribute is listed for Tris NP-40 Buffer (DCP-TNP1X). They also differ in size options — 100 ml and 500 ml versus 500 ml and 1000 ml. Any further difference in composition is not published in this source; check the individual product pages or contact support@diagnocine.com.
Seven components: AEBSF·HCl, a serine protease inhibitor; Aprotinin, which targets serine proteases and has anti-inflammatory properties; Bestatin, an aminopeptidase inhibitor; E-64, a cysteine protease inhibitor; EDTA, a metalloproteinase inhibitor; Leupeptin, which inhibits both serine and cysteine proteases; and Pepstatin A, an aspartic protease inhibitor.
Nonidet-P40 (NP-40) Buffer, RIPA Buffer, Cytoskeleton Extraction Buffer, and Tris Triton-X Buffer are each listed in 100 ml and 500 ml. Tris NP-40 Buffer is listed in 500 ml and 1000 ml. All four protease inhibitor cocktail pre-blends are listed at 10 x 10 mL. Every size appears on its own row in the catalog at the top of this page.
