Description Vitamin K1 (Phylloquinone) a fat-soluble, naturally occurring vitamin with antihemorrhagic and prothrombogenic activity.
In vitro Phylloquinone (Vitamin K1) is a prenylated naphthoquinone that is synthesized exclusively by plants, green algae, and some species of cyanobacteria, where it serves as a vital electron carrier in photosystem I and as an electron acceptor for the formation of protein disulfide bonds. Phylloquinone plays the role of a vitamin (vitamin K1) that is required for blood coagulation and bone and vascular metabolism in humans and other vertebrates. Phylloquinone from green leafy vegetables and vegetable oil represents the major dietary source of vitamin K for humans[1]. Vitamin K1 treatment causes a significant antiproliferative effect and induces apoptosis in Caco-2, HT-29, and SW480 cell lines, with the involvement of the MAPK pathway. A concomitant and significant decrease in the polyamine biosynthesis occurr[2].
In vivo Subjects who increased their dietary intake of vitamin K during the follow-up had a 51% reduced risk of incident diabetes compared with subjects who decrease or does not change the amount of phylloquinone intake[3]. Vitamin K supplementation reverses the high fat diet induced bone deterioration by modulating osteoblast and osteoclast activities and prevent bone loss in a high-fat diet-induced obese mice[4]. Application of vitamin K1 to the skin has been used for suppression of pigmentation and resolution of bruising. The effects produced by the topical vitamin K1 exhibit significant healing when compared with control group in parameters like wound contraction, epithelialization period, hydroxyproline content and tensile strength[5].
Cell Research Caco-2, HT-29, and SW480 cells are treated with increasing concentrations of vitamin K1 (10, 50, 100, and 200 μM) for 24 h, 48 h, and 72 h. MTT is added to each dish and incubated for 2 h at 37°C. At the end of the incubation period, the medium is removed. The plate is read at 570 nM[2].

Molecular Weight Calculator

Molarity Calculator allows you to calculate the

  • Mass of a compound required to prepare a solution of known volume and concentration
  • Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Concentration of a solution resulting from a known mass of compound in a specific volume
See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box


Calculator the dilution required to prepare a stock solution

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box
