Evacuated Blood Tubes
Capped sterile tubes with an internal vacuum that are commonly used to collect venous blood specimens; products are available in various materials, with various stopper types, and anticoagulants.
Evacuated blood tubes are sealed, single-use, capped tubes used with suitable collection needles and tubing for the safe and sterile collection of blood samples from human or animal subjects. They are partially evacuated to facilitate blood draw when the collection needle punctures the cap. The closure caps may be color-coded, depending on the tube additives or specific purpose.
Evacuated blood tubes are typically made of plastics such as polypropylene or PET to minimize the risk of breakage, although glass evacuated blood tubes are also available. Available as plain, empty tubes, many are pre-loaded with additives or preservatives that stabilize the blood sample or contain gel separators to facilitate the separation of blood cells from serum or plasma.
Evacuated blood tubes are widely employed in hospital blood collection (phlebotomy) departments and in other clinical, veterinary, and research settings. Once filled, evacuated blood tubes can be securely stored or transported for subsequent analysis of serum, plasma, or whole blood by clinical chemistry, blood counts, or other tests.

Cayman Chemical TNP-ATPsodIum salt 3.6mg
A derivative of ATP and an antagonist of the purinergic P2Y1, P2X3, and P2X2/3 receptors (IC50s = 6, 0.9, and 7 nM, respectively, in HEK293 cells expressing the human receptors); selective for these receptors over the purinergic P2X2, P2X4, and P2X7 receptors (IC50s = 2, 15.2, and >30 µM, respectively, in HEK293 cells expressing the human receptors); decreases acetic acid-induced calcium flux in 1321N1 cells expressing the P2X3 and P2X2/3 receptors (IC50s = 100 and 62 nM, respectively); reduces the number of abdominal constrictions induced by acetic acid in a mouse model of visceral pain (ED50 = 6.35 µmol/kg); ex/em maxima 403 and 547 nm, respectively; relative fluorescence increases four-fold when bound to IDE with an em maxima at 538 nm
