Description	Trastuzumab is a humanized monoclonal antibody for patients with invasive breast cancers that overexpress HER2. Trastuzumab has been clinically used to treat HER2 Positive Metastatic Breast Cancer and HER2 Positive Gastric Cancer.
Targets&IC50	HER2
Cell Research	The effects of trastuzumab and trastuzumab-F(ab′)2 on the growth of JIMT-1, SKBR-3, and BT-474 cells are evaluated using the AlamarBlue method. Exponentially growing cells are harvested and plated in single wells of a 96-well flat-bottomed tissue culture plate at defined densities, ranging from 4,500-8,000 cells per well depending on the cell line. After overnight culture, the regular medium is exchanged to medium containing 0, 1, 10, or 100 μg/mL trastuzumab or trastuzumab-F(ab′) 2. Cell viability is tested after 72 h of treatment. Fluorescence is detected at an excitation of 544 nm, and emission is detected at 590 nm[3]. Cell lines: JIMT-1, SKBR-3, and BT-474
Animal Research	Trastuzumab and trastuzumab-F(ab′)2 are given at a dose of 5 and 25 μg/g, respectively, by weekly i.p. injection. The five times greater amount of administered F(ab′)2 is chosen based on the different half-lives of IgG and F(ab′) F(ab′)2. Control mice are treated with weekly i.p. injection of 100 μL physiologic saline (saline) or rituximab (a humanized anti-CD20 antibody) at a dose of 5 μg/g. Animals are euthanized by CO2 inhalation[3].

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

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
