TBS Blocking Buffer with Gelatin (1%)
A research-grade Tris-buffered saline blocking reagent formulated with 1% gelatin, engineered for a stable pH of 7.4 and defined 50 mM Tris-Base / 150 mM Sodium Chloride molarity. It reduces non-specific binding and background noise across Western blotting, ELISA, and immunohistochemistry workflows. 0.1 µm filtration removes large particulates and aggregates, helping protect downstream applications.

Engineered where standard blocking buffers fail
Particulates and inconsistent pH can raise background noise and obscure target signal in sensitive immunoassays. TBS Blocking Buffer with Gelatin (1%) is built to remove those failure modes at the source.
0.1 µm filtered
0.1 µm filtration removes large particulates and aggregates, helping protect downstream applications.
Precise, stable pH
Formulated to a defined pH of 7.4 with 50 mM Tris-Base and 150 mM Sodium Chloride, maintaining a consistent environment for protein and antibody integrity.
Ultrapure-grade water
Prepared with Ultrapure Type 1 water (18.2 MΩ·cm) for sensitive assay reagents.
Low background for imaging & assays
The 1% gelatin matrix densely covers non-specific binding sites, improving signal-to-noise ratio for Western blot, ELISA, and IHC detection.
Defined, traceable composition
Every component — gelatin, Tris-Base, and Sodium Chloride — is disclosed at its exact working concentration with lot-based quality control.
Customization on demand
Alternate gelatin concentrations, additional salts, detergents, or pH adjustments can be formulated on request — contact support@diagnocine.com.

Where TBS Blocking Buffer with Gelatin (1%) is used
Formulated to block non-specific binding sites on membranes and microplates, DCP-GTBS1X supports a range of immunoassay workflows.
Dot Blot & Protein Arrays
Blocks unoccupied binding sites on membranes used for dot blots and protein arrays, helping reduce background.
Wash, Dilution & Reconstitution
Tris-buffered saline base with defined pH and ionic strength supports gentle wash and dilution steps ahead of blocking and detection.
iPSC-Derived Model Immunostaining
Reduces non-specific antibody binding when staining iPSC-derived neuron, cardiomyocyte, and hepatocyte cultures.
Endothelial & Primary Cell Immunolabeling
Supports low-background immunolabeling of endothelial and primary cell cultures.
ELISA, Western Blotting & Blocking
The 1% gelatin matrix blocks unoccupied binding sites on membranes and microplates, reducing background and improving assay signal-to-noise.
Microscopy & Optical Detection
Low-background blocking supports clearer immunofluorescence and chromogenic detection in microscopy-based readouts.
