Family Snapshot

The step between the gel and the membrane

Tris-based transfer buffers are integral to the Western blotting process, facilitating the efficient transfer of proteins from gels to membranes while maintaining protein integrity. The choice of buffer composition may need to be optimized based on specific proteins of interest and experimental requirements. For challenging transfers, modifications such as adjusting methanol concentration or adding SDS may be necessary to improve transfer efficiency.

  • Four products, eight catalog entries. Each product is listed in 500 ml and 1000 ml.
  • Three transfer chemistries: Tris-CAPS, Tris-Glycine (non-denaturing), and Bis-Tris.
  • Two working formats. Two products ship as 1X ready-to-use; two ship as 10X concentrates that are diluted before use.
  • The Tris-Glycine non-denaturing formulation is offered in both formats — as a 1X buffer and as a separate [10X] concentrate with its own catalog number.
  • 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.
  • Optimization is expected. Buffer composition may need to be tuned to the specific protein of interest, and for challenging transfers the methanol concentration can be adjusted or SDS added.

Check the concentration before you compare bottle sizes. A 10X concentrate is diluted before use, so 500 ml of a 10X product makes 5 litres of working buffer and 1000 ml makes 10 litres, while a 1X product is used as supplied. Two products in this family are 10X and two are 1X — the tag on each catalog row tells you which. No pH figure is published for this family; for the pH or the exact formulation of a specific product or lot, contact support@diagnocine.com.
Why the Transfer Buffer Matters

Six things the source says this step has to do

Transfer is the point where a good gel becomes a good blot — or does not. Each card below is one property the source attributes to Tris-based transfer buffers.

swap_horiz

Integral to Western blotting

The source's own framing. The transfer buffer is not a consumable detail — it is the medium the entire blot depends on, sitting between electrophoresis and detection.

north_east

Efficient transfer, gel to membrane

The buffer facilitates the efficient transfer of proteins from gels to membranes. Efficiency here is recovery: protein left behind in the gel never reaches the antibody.

shield

Protein integrity maintained

Transfer has to move the protein without damaging it. The source names maintaining protein integrity as a defining requirement of the step, alongside efficiency.

target

Composition follows the target

The choice of buffer composition may need to be optimized based on the specific proteins of interest and the experimental requirements — which is why this family carries three chemistries rather than one.

water_drop

Methanol is a lever

For challenging transfers, adjusting the methanol concentration is one of the two modifications the source names as a way to improve transfer efficiency.

tune

SDS is the other lever

Adding SDS is the second named modification for challenging transfers. Both levers are expected adjustments, not signs that something has gone wrong.

Pick the chemistry first, then the format

Two decisions, in order. The chemistry — Tris-CAPS, Tris-Glycine non-denaturing, or Bis-Tris — is a protocol decision driven by the protein of interest. The format — 1X ready-to-use or 10X concentrate — is a throughput and storage decision, and the Tris-Glycine non-denaturing formulation is available either way.

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 transfer buffer floods the gel, the membrane, and the stack, so anything it carries ends up on the blot surface you are about to image.

  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 on a blot

Particulate that settles on a membrane during transfer does not wash off cleanly and shows up later as speckle in the imaged lane. An ultra-filtered, ultra-low-particulate buffer keeps that background off the membrane before blocking and detection ever begin.

Transfer Optimization

The three levers the source names

Transfer buffers are expected to be tuned rather than used blind. These are the adjustments the source identifies, reproduced as published.

Lever When it applies What the source says
Buffer composition Any transfer The choice of buffer composition may need to be optimized based on specific proteins of interest and experimental requirements.
Methanol concentration Challenging transfers Adjusting methanol concentration may be necessary to improve transfer efficiency.
SDS Challenging transfers Adding SDS may be necessary to improve transfer efficiency.
The source gives no target values. It names methanol concentration and SDS as levers but publishes no percentage, molarity, or recommended range for either, and none is supplied here. For a formulation with a specific methanol or SDS content, or for the composition of a given product, contact support@diagnocine.com.

FAQ

Frequently asked questions

The questions that come up most often when choosing a transfer buffer.

Tris-based transfer buffers are integral to the Western blotting process, facilitating the efficient transfer of proteins from gels to membranes while maintaining protein integrity. Both halves matter: the buffer has to move the protein out of the gel and onto the membrane, and it has to do so without damaging what it moves.
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 and no methanol or SDS content are published for this family, so none are stated here. Request lot documentation at support@diagnocine.com.
The source names three levers. First, buffer composition, which may need to be optimized based on the specific proteins of interest and the experimental requirements. Then, for challenging transfers specifically, two modifications: adjusting the methanol concentration, or adding SDS. It publishes no target values for either, so treat them as directions to test rather than settings to copy.
Concentration. FluxMPS™ Tris-Glycine Non-Denaturing Buffer (DCP-TGNDB1X) is the 1X ready-to-use buffer; FluxMPS™ Tris-Glycine Non-Denaturing Buffer [10X] (DCP-TGNDRB10X) is the 10X concentrate of the same chemistry, diluted before use. Both are listed in 500 ml and 1000 ml. The names differ only by the [10X] suffix, so check the catalog number before ordering.
A 10X concentrate is diluted ten-fold before use, so 500 ml yields 5 litres of working buffer and 1000 ml yields 10 litres. A 1X product is used as supplied. This is the arithmetic of the published concentration, not a separate specification — for dilution instructions for a specific product, see its product page or contact support@diagnocine.com.
The source publishes no comparison between the three, and none is invented here. It states only that the choice of buffer composition may need to be optimized based on the specific proteins of interest and the experimental requirements. What the catalog does tell you is the coverage: Tris-CAPS in one product as a 10X concentrate, Tris-Glycine non-denaturing in two products covering both formats, and Bis-Tris in one product as 1X ready-to-use. For help matching a chemistry to a target, contact support@diagnocine.com.
All four products are listed in 500 ml and 1000 ml, which is why the family has eight catalog entries. Every size appears on its own row in the catalog at the top of this page, with its own catalog number and its own link to the product page.
