| 产品名称： | HT-2 clone A5E |
|---|---|
| 商品货号： | TS211810 |
| Organism： | Mus musculus, mouse |
| Tissue： | spleen |
| Cell Type： | IL-2 dependent T lymphocyte |
| Product Format： | frozen |
| Morphology： | lymphoblast |
| Culture Properties： | suspension |
| Biosafety Level： | 1
Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country. |
| Strain： | C57BL |
| Applications： | The line is dependent on IL-2 for growth and can be used to measure IL-2 activity in a very rapid and sensitive assay. The cells are commonly used for characterization of lymphokines and cytokines. |
| Derivation： | The HT-2 cell line was derived in 1979 by J. Watson at the University of Auckland from a culture of C57BL spleen cells activated by sheep erythrocytes in the presence of IL-2.
This cell line was originally deposited as derived from the BALB/c strain of mice. Recent testing at ATCC and by the NIST Mouse STR Consortium using mouse STR technology has shown that the STR profile has more alleles in common with a C57BL mouse strain rather than BALB/c.

| Antigen Expression： | Thy-1 |
| Receptor Expression： | interleukin 2 (IL-2) |
| Comments： | The A5E clone was selected to provide a homogeneous population that is highly sensitive to IL-2.
In addition to IL-2, substantial proliferation is seen in the presence of interleukin 4 (interleukin-4, IL-4, also known as BSF-1).
|
| Complete Growth Medium： | RPMI 1640 medium with 2 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate, 4.5 g/L glucose, 10 mM HEPES and 1.0 mM sodium pyruvate and supplemented with 0.05 mM 2-mercaptoethanol, 100-200 IU/ml IL-2, 90%; fetal bovine serum, 10%
Alternatively, IL-2 in the form of Rat T-STIM factor with Con A (available from Becton Dickinson, Cat.# 354115) may be used at 10% by volume.
|
| Subculturing： | Cultures can be maintained by addition or replacement of fresh medium. Subcuture every two days at 3.5 x 10 4 viable cells/mL. Medium Renewal: Every 2 to 3 days |
| Cryopreservation： | Freeze medium: complete growth medium, 95%; DMSO, 5% |
| Culture Conditions： | Temperature: 37°C |
| Name of Depositor： | JF Weaver, A Creasey |
| Deposited As： | Mus musculus |
| Year of Origin： | 1979 |
