This column utilizes size exclusion chromatography (SEC) principles to resolve compounds based on their molecular size, making it an invaluable tool in various biochemical and biophysical research applications. The "HR" designation signifies high resolution, a critical factor for achieving clean separations of closely sized molecules.
The Superdex Peptide HR 10/30 column is part of a broader family of Superdex chromatography media developed by Cytiva (formerly GE Healthcare Life Sciences)Size exclusion chromatography on Superdex Peptide HR .... These columns are pre-packed, offering convenience and ensuring consistent performance. The "10/30" in the name refers to the column dimensions: a 10 mm inner diameter and a 30 cm lengthDesigned for high resolution in small-scale preparative purification and analysisfor sample volumes up to 500μL. Replacement for Superdex peptide columns.. This size is typical for analytical and small-scale preparative applications, balancing resolution with sample throughput.
The packing material within the Superdex Peptide HR 10/30 is specifically engineered for effective separation of peptides, which generally range in molecular weight from approximately 100 to 5000 Da. This size range is crucial for researchers working with synthesized peptides, fragments of larger proteins, or naturally occurring small peptide hormones and signaling molecules.
The primary application of the Superdex Peptide HR 10/30 column lies in its ability to perform high-resolution gel filtration, also known as size exclusion chromatography (SEC). This method separates molecules based on their hydrodynamic volume. Smaller molecules can penetrate the pores of the stationary phase more effectively, leading to a longer retention time, while larger molecules are excluded from the pores and elute earlier.Characteristics of Superdex® prep grade media for gel ...

It's important to distinguish the Superdex Peptide HR 10/30 from other Superdex columns. For instance, Superdex 75 HR 10/30 and Superdex 200 HR 10/30 columns are designed for larger biomolecules like proteins. Superdex 75 is typically used for proteins in the range of 1,500 to 30,000 Da, while Superdex 200 handles proteins from 5,000 to 600,000 Da.Superdex®Peptide 10/300 GLis a prepacked Tricorn high-performance column for high-resolution gel filtration of peptides and other small biomolecules with ... The Superdex Peptide HR 10/30, with its specific pore size distribution, is optimized for the smaller molecular weight range characteristic of peptides.Size exclusion chromatography on Superdex Peptide HR ...
Furthermore, it's worth noting that some Superdex Peptide columns, like the Superdex Peptide 10/300 GL, have been or are being discontinued and replaced by newer "Increase" versions, such as the Superdex 30 Increase 10/300 GL. These newer columns often offer improved resolution, faster run times, and enhanced performance compared to their predecessors. While the Superdex Peptide HR 10/30 is still a widely used and effective column, users should be aware of these advancements and potential replacements for future applications.
When using the Superdex Peptide HR 10/30, factors such as flow rate, mobile phase composition, and sample loading are critical for achieving optimal separation. The column's performance is often evaluated by constructing calibration curves using peptide standards of known molecular weights. This process helps verify the column's integrity and suitability for specific analytical tasks.
The column's "high resolution" capability means it can effectively differentiate between peptides with subtle differences in size, which is crucial in applications like peptide mapping or analyzing post-translational modifications. The "HR" designation often implies a smaller particle size of the stationary phase, contributing to better efficiency and resolution, albeit sometimes at the cost of higher backpressure.In summary, SPP substitution for FM promoted intestinal health, liver lipid metabolism and reduced liver fat accumulation for juvenile pompano T. ovatus, with ...
