α-L-Rhamnose monohydrate

Customer Review

Based on 1 Customer Validation

α-L-Rhamnose monohydrate is a neutral sugar present in plants, animals, viruses and bacteria. α-L-Rhamnose monohydrate is a ligand for α-L-rhamnose-recognizing lectin sites, trigger intracellular signaling pathways. α-L-Rhamnose monohydrate induces rhaE and rhaA expression as a specific carbon source in Aspergillus nidulans, while glucose inhibits its cellular uptake. α-L-Rhamnose monohydrate induces rapid and transient increases in intracellular free Ca²⁺ concentration in normal human dermal fibroblasts.

In Vitro

α-L-Rhamnose (10 μg/mL; ~15 minutes) monohydrate triggers early, transient increases in intracellular free Ca²⁺ concentration in a subset of normal human dermal fibroblasts (NHDFs)^[1].
α-L-Rhamnose (1% w/v; 1-24 h) monohydrate induces rapid transcriptional upregulation of rhaE and rhaA in both Aspergillus nidulans wild-type and creA^d30 derepressed strains, with greater transcript accumulation observed in the creA^d30 strain^[2].
α-L-Rhamnose (1% w/v; up to 48 h) monohydrate is consumed by Aspergillus nidulans wild-type and creA^d30 derepressed strains over 48 h, inducing extracellular α-L-rhamnosidase activity, while concurrent glucose presence blocks it monohydrate uptake and enzyme activity in both strains^[2].
α-L-Rhamnose (1% w/v; up to 30 h) monohydrate is consumed by Aspergillus nidulans creA^d30 derepressed strain over 30 h, inducing α-L-rhamnosidase activity, while concurrent ethanol presence does not block uptake but still prevents enzyme activity^[2].

Stock Solution Working Solution

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.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.5 mg/mL (13.72 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2.5 mg/mL (13.72 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (13.72 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Working Solution

For the following dissolution methods, please prepare the working solution directly:

It is recommended to prepare fresh solutions and use them promptly within a short period of time.

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.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
