In vivo In severe acute pancreatitis (SAP) group, the pathological change increased with time after modeling. Pathological change of the pancreas tissue in 3-methyladenine group was milder than those in the SAP group at both 12 and 24h [4]. 3-MA pretreatment significantly aggravated neurological symptoms when compared with the SAH + vehicle group. a large number of dying neurons from the SAH + 3-MA group showed cell shrinkage, chromatin condensation at the nuclear membrane and nuclear and cellular fragmentation, which suggest that the neurons were undergoing apoptotic cell death [5].
Kinase Assay Protein degradation assay: HeLa cells are radiolabeled for 24 hours with 0.05 mCi/mL l-[U- 14C]valine. At the end of the labeling period, cells are rinsed three times with PBS. Cells are incubated for the designated times in either full medium or EBSS with or without the presence of 10 mM 3-Methyladenine.
Cell Research
Cell (such as HeLa cell) viability is determined by a trypan blue exclusion assay. Briefly, after treated with 3-Methyladenine, both adherent and floating cells are collected and suspended in phosphate buffered saline (PBS, pH 7.4) at a final density of 1-2 × 106/mL. An equal volume of 0.4% trypan blue solution (w/v, in PBS) is added to the cell suspension and mixed thoroughly. After incubation at room temperature for 3 min, cell counting is performed using a hemacytometer. (Only for Reference)

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

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
