The Tear Protein Extraction Kit developed by MtoZ Biolabs is specifically designed for the rapid isolation of high-quality proteins from tear samples. This kit effectively removes impurities and enriches low-abundance proteins. It supports noninvasive diagnostic research and biomarker discovery in ophthalmic diseases.
Product Overview
Tear fluid, one of the most valuable noninvasive biofluids, is produced by the lacrimal glands, conjunctival goblet cells, and associated ocular glands. Its protein composition reflects ocular surface immunity, inflammatory conditions, and tear film homeostasis. However, the physicochemical properties of tears present several challenges for efficient protein extraction.
1. Extremely Low Protein Abundance
The total protein concentration in tear fluid is significantly lower than that in plasma or saliva. Due to the limited sample volume, proteins are easily lost during handling, which requires highly sensitive extraction methods with excellent recovery efficiency.
2. Lipid and Salt Interference
Tear fluid contains tear film lipids, salts, and small-molecule metabolites that affect protein solubility and compromise the accuracy and stability of analytical techniques such as SDS-PAGE and LC-MS/MS.
3. Sample Instability
Tear samples are present in small volumes and evaporate quickly, which means that proteins may degrade or undergo concentration changes without proper and timely processing.
Advantages
1. High Recovery
MtoZ Biolabs' Tear Protein Extraction Kit employs enhanced lysis and enrichment systems that achieve efficient recovery even from minimal tear volumes.
2. Efficient
The purification procedure produces cleaner protein extracts that enhance sensitivity in downstream assays.
3. Protective
Built-in stabilizers and protective components prevent protein degradation or denaturation from the earliest processing step, ensuring accurate and reproducible analytical results.
