The Formalin-Fixed Tissue Protein Extraction Kit from MtoZ Biolabs is designed to efficiently release high-quality proteins from formalin-preserved tissues for downstream proteomics and biochemical analysis.
Product Overview
Formalin-fixed tissues pose substantial challenges during protein extraction due to fixation-induced chemical modifications and structural rigidity. Common issues include:
1. Extensive Protein Crosslinking Leading to Poor Solubility
Formaldehyde creates covalent crosslinks between proteins and nucleic acids, restricting solubilization and reducing extraction efficiency, especially for low-abundance proteins.
2. Structural Alterations That Limit Epitope Accessibility
Fixation distorts native protein conformations, masking critical epitopes required for antibody binding and reducing signal quality in immunoassays.
3. Residual Fixatives and Tissue Rigidity
Fixed samples retain embedded chemical residues and exhibit reduced tissue permeability, hindering buffer penetration and complicating downstream electrophoresis or LC-MS workflows.
Advantages
1. Enhanced Reversal of Fixation-Induced Crosslinks
A specialized extraction buffer promotes controlled reversal of formaldehyde crosslinks, improving protein solubility and preserving functional epitopes.
2. Improved Tissue Permeabilization and Lysis
Optimized reagents soften rigid tissue structures and facilitate thorough buffer penetration, ensuring more complete protein recovery from fixed samples.
3. Cleaner Lysates for Reliable Analysis
The Formalin-Fixed Tissue Protein Extraction Kit from MtoZ Biolabs minimizes interference from residual fixatives and produces low-viscosity extracts suitable for electrophoresis, immunoblotting, and mass spectrometry.
