| Derivation |
CD45 deficient cells were isolated using a fluorescence activated cell sorter, and cloned by limiting dilution.
The Jurkat cell line was established from the peripheral blood of a 14 year old boy by Schneider et al., and was originally designated JM.
The line was isolated after gamma irradiation of E6-1 followed by lysis of CD45 positive cells with the GAP 8.3 monoclonal antibody (see ATCC HB-12) and complement. |

| Comments |
The J45.01 cell line is a CD45 deficient variant of the E6-1 clone of Jurkat (ATCC TIB-152).
CD45 deficient cells were isolated using a fluorescence activated cell sorter, and cloned by limiting dilution.
The cells express the T cell antigen receptor (TCR, CD3), CD2 and CD28 at levels comparable to the parental line, but only 5 to 8% as much CD45.
Loss of CD45 diminishes TCR - CD2 signal transduction, thus the cells are inducible for interleukin 2 (IL-2) production with calcium ionophores and phorbol esters, but not with TCr or CD2 stimulation. |
| Complete Growth Medium |
The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, ATCC 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (ATCC 30-2020) to a final concentration of 10%.
