產(chǎn)品名稱 HT-2 clone A5E
商品貨號(hào) B164801
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.
