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.
Types of Evacuated Blood Collection Tubes
• Red top: plain tubes without additives; for serum samples
• Purple top: contain EDTA anticoagulant; for clinical hematology procedures
• Green top: contain heparin; for plasma samples
• Gray top: with added fluoride or oxalate; for glucose determinations
• Blue top: with sodium citrate; for coagulation testing
• Other additives and colored closures

Vector Biolabs Signal transducer and activator of transcription 2 Adenovirus (Ad-STAT2)
Stats (signal transducers and activators of transcription) are tyrosine phosphorylated transcription factors activated by JAK family kinases. Various ligands, including interferons and growth factors, induce activation of the JAK kinases, which induce Stat activation. Stat1 and Stat2 are induced by IFN-α and form a heterodimer that is part of the ISGF-3 transcription factor complex. Stat3β is activated by EGF and IL-6. Stat3α is activated by EGF. Highest expression of Stat4 is observed in the testis and myeloid cells. IL-12 has been identified as an activator of Stat4. Stat5 can be activated by prolactin and by IL-3. Stat6 is involved in IL-4 activated signaling pathways. Stat-1 and Stat-3 bind the serum-inducible element (SIE) and GAS/ISRE elements are also known to be STAT-binding sites.
