Menaquinone-7  (Synonyms: Vitamin K2-7; Vitamin K2(35); Vitamin MK-7)

Cat. No.: HY-112499 Purity: ≥98.0%
COA Handling Instructions

Menaquinone-7 (Vitamin K2-7), belongs to a class of K2-vitamin homologs (orally active), is originally discovered as the anti-hemorrhagic factors. Menaquinone-7 inhibits osteoclast bone resorption in vitro and stimulates bone formation in femoral tissue of aged female rats. Menaquinone-7 has a well-researched potential in the prevention of aging-induced bone degeneration. Menaquinone-7 is also a pharmacological option for activating Gla matrix protein and intervening in the progression of calcific aortic stenosis (CAVS).

Description

Menaquinone-7 (Vitamin K2-7), belongs to a class of K2-vitamin homologs (orally active), is originally discovered as the anti-hemorrhagic factors. Menaquinone-7 inhibits osteoclast bone resorption in vitro and stimulates bone formation in femoral tissue of aged female rats. Menaquinone-7 has a well-researched potential in the prevention of aging-induced bone degeneration. Menaquinone-7 is also a pharmacological option for activating Gla matrix protein and intervening in the progression of calcific aortic stenosis (CAVS)[1][2][3][4][5].

In Vitro

Menaquinone-7 (0.01-10 μM; 7 days) inhibits osteoclast-like cell formation in marrow cultures[1].
? Menaquinone-7 (10 μM) promotes the expression of tenascin C and increases phosphorylated Smad1 level in MC3T3E1 cells[2].
? Menaquinone-7 (1, 10 μM) significantly enhances the anabolic effect on the femoral calcium content in the presence of phytoestrogen genistein (1, 10 μM)[3].

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.

  • Protocol 1

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

    Solubility: 0.54 mg/mL (0.83 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 0.54 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.4 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.
  • Protocol 2

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

    Solubility: ≥ 0.54 mg/mL (0.83 mM); Clear solution

    This protocol yields a clear solution of ≥ 0.54 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 (5.4 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
