RALF1 peptide
Based on 1 Customer Validation
RALF1 peptide, a polypeptide found in plant kingdom (as well as in fungi and bacteria), is a FERONIA (FER) modulator. RALF1 peptide mediates rapid net H+ influx across the plasma membrane, apoplast alkalinization, rapid reversible root growth inhibition, and non-transcriptional regulation.RALF1 peptide up-regulates auxin biosynthesis genes, activates canonical TIR1/AFB auxin signaling, and mediates sustained root growth inhibition. RALF1 peptide can be used for research on the regulation of plant growth and development.

Biological Activity
Description
In Vitro
RALF1 peptide (5 μM; 3 h) induces FER-dependent up-regulation of YUC5, YUC6, and YUC11 gene expression in Arabidopsis thaliana roots, with no direct effect on TAA/TAR gene expression, after 3 h of treatment[1].
RALF1 peptide (5 μM; 3 h) alters auxin homeostasis in Arabidopsis thaliana root tips by increasing IAA levels and its catabolites/conjugates in a FER-dependent manner, after 3 h of treatment[1].

Solvent & Solubility
In Vitro:
DMSO : 100 mg/mL (18.30 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2 mg/mL (0.37 mM); Clear solution
This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2 mg/mL (0.37 mM); Clear solution
This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
