In the realm of biochemical research, the study o Fig. 4. Peptide maps of the 44.7 kDA and 40.2 kDA proteins f specific protein fragments and signaling molecules is critical for understanding cellular mechanisms. When we analyze the 4 kDa peptide, we are looking at a specific class of compounds that often serve as vital tools in structural biology and signaling studies. As someone deeply involved in the procurement and evaluation of research-grade materials, I have found that distinguishing between molecular weights is essential for successful experimental outcomes.
The Biological Significance of the 4 kDa Peptide
One of the most well-docum kDa peptide involved in the interaction with its binding protein ented instances of a molecule in this weight class is the soybean-derived 4 kDa disulfide-rich peptide. In academic literature, this specific molecule is a hormone-like peptide that plays a sophisticated role in plant physiology. Research has demonstrated that this molecule is a ligand for the 43-kDa basic glycoprotein (43k-P), which is commonly found in legumes.
Furthermore, this interaction is highly specific; the peptide is a ligand for the 43-kDa protein in legumes that functions as a protein kinase. This kinase is essential for controlling cell proliferation, and the larger structure is capable of interaction with a 4-kDa hormone-like peptide (often referred to as leginsulin).

Analytical Tools: FITC-Dextran and Molecular Weight Standardization
For those of us working in laboratories, the term kDa (kilodalton) is the industry standard for expressing the molecular weight of peptides and proteins. When conducting assays, researchers often utilize markers or probes to calibrate their results. For example, FITC-dextran sulfate, 4kDa is a popular choice for researchers needing a reliable fluorescent standard.
This specific compound functions as an anionic fluorescent probe used to study drug delivery systems and biological encapsulation. By utilizing a 4 kDa marker, one can ensure that the electrophoresis or chromatography processes are calibrated correctly, helping to distinguish between different peptide fragments—such as those ranging from four amino acid motifs to larger recombinant structures.
Navigating Research-Grade Materials
When sourcing materials, it is important to be aware of the variety of products available. For instance, you might encounter Recombinant Human TCF-4 protein or specialized items like a 47 Kda Protein for metabolic research. My experience has taught me that the purity and documentation of these peptides are paramount. Whether you are using a synthetic peptide for use as a blocking control in an antibody assay or investigating the effects of a Teduglutide peptide (which enhances intestinal absorption and mucosal growth in specific models), the 4 kDa threshold serves as a vital reference point.
Technical Considerations in Protein Analysis
