MtoZ Biolabs’ GST Tagged Protein Purification Kit is designed for rapid purification of GST-tagged fusion proteins. This kit helps efficiently obtain high-purity recombinant proteins and is widely used in enzymatic studies, interaction validation, and structural and functional analyses.
Product Overview
When preparing recombinant proteins, performing enzyme assays, or running GST pull-down interaction validation, conventional GST affinity purification often faces the following challenges:
1. Complex Lysate Background
High levels of host proteins, nucleic acids, and other impurities can lead to nonspecific adsorption, reducing purity and compromising downstream stability.
2. Variable Target Solubility
Some GST fusion proteins may still aggregate or form insoluble fractions, resulting in low recovery and larger batch-to-batch variability.
3. Difficult Balance Between Purity and Yield
Binding and washing conditions are hard to optimize; overly stringent washing lowers recovery, while insufficient washing increases background.
4. Elution not Compatible with Downstream Steps
Elution conditions may affect enzyme activity assays, interaction studies, or structural work, requiring additional desalting or buffer exchange.
5. Operational Details Affect Reproducibility
Differences in resin condition, incubation time, and wash volume can translate into variability in final yield and purity.
Advantages
1. Fast Setup, Fewer Steps
Quick to start with a short workflow, suitable for routine and batch purification.
2. Low Carryover, Cleaner Background
Cleaner background with less interference from nonspecific adsorption.
