Learn the best practice for adding materials that require dilution or aliquoting

For Single Ingredient materials that require some aliquoting or dilution, (such as A14700 or Vitronectin) we recommend you first add the stock (lyophilized or concentrated) material as a Single Ingredient material (i.e., A14700 - 60ul)

You can then build Recipe Materials for the working aliquots that include the concentration/size of the aliquot in the material name.

For example:  To add Vitronectin and Vitronectin-coated plates as materials in CultureTrax, add the Vitronectin stock vial as a Single Ingredient and add a Recipe Material for the smaller Vitronectin aliquots. You could then add a Recipe Material for coated plates from the aliquots.

  1.  Add the Vitronectin stock as a new Single Ingredient material named "Vitronectin 0.5 mg/ml Stock"

  2. Add/Build a new Recipe Material named "Vitronectin - 60 ul aliquots" by adding the ingredient "Vitronectin 0.5 mg/ml Stock" (#1 above) and describing the aliquoting procedure and volumes.

  3. Add/Build a new Recipe Material named "Vitronectin coated 6-well plates" by combining the Recipe Material "Vitronectin aliquots" (#2 above) with the additional Single Ingredient materials "Cell Culture Plates, 6-well, Flat Bottom (Costar)" and "DBPS, no calcium, no magnesium", describing your volumes and plate coating procedure.

For example:  To add a Rock Inhibitor (Y27632) as a material in CultureTrax, you would add the lyophilized stock as a Single Ingredient and the working aliquots as Recipe Material.

  1. Add the stock Rock Inhibitor material as a Single Ingredient material named "Y27632 -  1mg stock".

  2. Add DPBS (the diluent) as a Single Ingredient material 

  3. Add/Build a Recipe Material named "Y27632 - 5mM Aliquots" by combining the Y27632 - 1mg stock (#1 above) with DPBS (#2 above), describing the volumes, concentrations, prep procedure and storage location of the aliquots here.
