Description
Our BMS-202 powder is BMS-202 supplied as loose powder. Each batch is tested by LC-MS to 99% purity or higher. It’s $399.99. It’s sold for laboratory research only.
The same compound comes in other formats too: BMS-202 liquid and BMS-202 capsules. You’ll find similar products in our research chemical powders range.
What is BMS-202?
BMS-202 is a small-molecule inhibitor of the PD-1/PD-L1 interaction from Bristol Myers Squibb. It binds PD-L1 and pulls two PD-L1 molecules together, which blocks PD-1 binding.
It’s a standard tool in cancer immunology labs.

Weighing and handling BMS-202 powder
Loose powder is the most flexible way to buy BMS-202. You can weigh any amount you need, dissolve it in your own solvent, or fill your own capsules. It’s also the cheapest format per milligram.
For small amounts you’ll want a scale that reads to at least 0.01g, and ideally 0.001g. Our digital scale and micro scoops make it easier to get consistent measurements. Weigh onto clean weighing paper, and close the bag or jar straight after so the powder doesn’t pick up moisture.
Making a solution from BMS-202 powder
To make a stock solution, decide on the final volume and concentration first. For 30mL at 10mg/mL you’d weigh 300mg of BMS-202, dissolve it in about 25mL of solvent, then top up to exactly 30mL.
Check the compound’s solubility in your chosen solvent before you start, and try a small test amount first. Store the finished solution in a labelled glass bottle.
Purity testing for BMS-202
We test each batch of BMS-202 by LC-MS, which pairs liquid chromatography with mass spectrometry. The chromatography splits the sample into its components and the mass spectrometer identifies them, which tells you both identity and purity. This batch came in at 99% or higher.
Small differences between batches are normal, so write the batch number from the label into your records. If something looks wrong when your order arrives, like discoloured powder or a cloudy solution, set it aside and don’t use it.
How to store BMS-202
Store it frozen, at -10°C or colder. Use a clean, dry scoop each time, and reseal the container straight away. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.
Common questions about the BMS-202 powder
What can I dissolve BMS-202 powder in?
That depends on the compound’s solubility and your protocol. Check the solubility data for your solvent first, and test a small amount before making up a full batch.
What scale do I need?
One that reads to 0.01g at minimum, and 0.001g for very small amounts. Our pocket scale reads to 0.01g.
