Overview of Recombinant Human GPALPP1 Protein

Recombinant Human GPALPP1 Protein (SKU: rp376162) is produced for research applications requiring a well-defined, human-derived protein target. GPALPP1 (GPALPP Motifs Containing Protein 1) is a human protein whose precise biological roles remain under active investigation. The recombinant form provides researchers with a consistent and reproducible source of this protein for biochemical characterization, binding studies, antibody validation, and related assays.

This product is intended for research use only and is not approved for diagnostic or therapeutic applications. Researchers should consult the current product datasheet for lot-specific information including purity, concentration, and formulation details.

Reconstitution Protocol

Proper reconstitution is critical to maintaining protein integrity and biological activity. Follow the steps below:

1. Equilibrate to room temperature: Allow the lyophilized protein vial to equilibrate to room temperature for 10–15 minutes before opening, to minimize condensation and protein aggregation upon reconstitution.
2. Centrifuge the vial: Briefly centrifuge the sealed vial (e.g., 5–10 seconds at low speed) to pellet any lyophilized material adhering to the cap or sides.
3. Add reconstitution buffer: Reconstitute the protein by adding sterile deionized water or the buffer recommended on the product datasheet (typically PBS, pH 7.4, with a carrier protein such as 0.1% BSA if required). Add the buffer slowly down the side of the vial to avoid foaming.
4. Gently mix: Do not vortex. Gently swirl or pipette the solution to achieve complete dissolution. Allow 5–10 minutes for full solubilization if needed.
5. Verify reconstitution: The solution should appear clear. Discard if visible particulates or cloudiness persist after gentle mixing.

Note: Refer to the lot-specific Certificate of Analysis (CoA) for the recommended reconstitution volume and final concentration.

Storage and Stability

Correct storage conditions are essential to preserve protein activity over time:

• Short-term storage (≤1 week): Store at 4°C if the protein will be used within one week of reconstitution. Avoid prolonged storage at 4°C, as protein degradation may occur.
• Long-term storage: Aliquot the reconstituted protein into single-use volumes appropriate for your experimental needs and store at -20°C or preferably -80°C.
• Avoid freeze-thaw cycles: Repeated freeze-thaw cycles can cause protein denaturation, aggregation, and loss of activity. Always use single-use aliquots.
• Carrier protein: Adding a carrier protein (e.g., 0.1% BSA) to the reconstitution buffer can improve stability during storage, particularly for low-concentration aliquots.
• Lyophilized stock: The unopened lyophilized protein should be stored at -20°C or -80°C as indicated on the product label. Protect from moisture.

Refer to the product datasheet for lot-specific stability data and recommended storage duration.

Experimental Applications and Usage Guidelines

Recombinant Human GPALPP1 Protein is suitable for a range of in vitro research applications. Researchers should optimize conditions for their specific assay format:

• Protein–protein interaction studies: Use purified GPALPP1 protein as bait or prey in pull-down or co-immunoprecipitation experiments to identify binding partners.
• Antibody validation: Use as a positive control antigen for ELISA, Western blot, or immunofluorescence assays to confirm antibody specificity.
• Biochemical assays: Evaluate enzymatic activity, post-translational modifications, or structural properties using standard biochemical techniques.
• Cell-based studies: Where biologically active protein is required, confirm activity using a functional assay validated for GPALPP1 prior to use in cell-based experiments.

Working concentration: Optimal working concentrations should be determined empirically for each application. Refer to published literature or the product datasheet for suggested starting concentrations.
