KRAS is the most frequently mutated oncogene in tumors, with 20% of all solid tumors containing oncogenic KRAS mutations. One single type of KRAS mutation — called KRAS G12C — accounts for about 44% of all KRAS mutations. G12C is a single point mutation with a glycine-to-cysteine substitution at codon 12[1].

  • Reconstitution Calculator

  • Dilution Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
