Bench Tools

Free, open source tools for cell therapy and biologics research. Each runs entirely in your browser: nothing you enter ever leaves your computer.

• Antigen Density Calculator

  Converts flow cytometry median fluorescence intensity into antibody binding capacity against a calibrated bead standard, reports the uncertainty of that conversion, and withholds a figure it cannot defend.

• Molarity Converter for Biologics

  Converts between mass concentration and molar concentration for a protein or antibody, given its molecular weight, its source, and what that weight is the mass of.

• Antibody Titration Planner

  Plans an antibody titration series for flow cytometry: the concentration at each point, in every form the bench and the method record require, for the staining volume and cell number you declare.

• Dilution Planner

  Plans the volumes to combine to reach a target concentration, or an ordered series of them, from a stated stock, including the intermediate a step needs when its transfer is too small to pipette.

• Reconstitution

  The diluent volume to add to a vial for a target concentration, or the concentration a stated volume gives, correct for what the number on the vial is the amount of and for the volume the dry solids occupy.
