Some groups use peptide pulsed splenocytes as the targets

It looks like it could be extremely useful to buy the "Anti-Mouse
OVA257-264 (SIINFEKL) peptide bound to H-2Kb PE"

These people use EL4 cells (T lymphocyte lymphoma cells from C57BL/6N as
targets)

In this paper they use B16 (melanoma cells from C57BL/6J mice) pulsed
with the SIINFEKL peptide along with OT-1 CD8+ T cells from C57BL/6 mice.

B16 melanoma cells have the H2-Kb haplotype
Both C57BL/6 and C57BL/6J have the H2-Kb haplotype
I wasn't sure exactly what OT-1 CD8+ T cells are. In the paper they state
"OT-1 CD8+ T cells, harvested from spleens of C57BL/6 mice, expressa
transgene encoding a TCR that specifically recognizes SIINFEKL peptide
bound to MHC-I H-2kb (Hogquist et al., 1994)." From what I understand,
they are doing something a little different with their "OT-1 CD8+" cells
that we won't need to do. We will just need to immunize our C57BL/6 mice
like we stated before.
They don't say whether they use B16-F0, B16-F1, or B16-F10 cells. In our
lab we have B16-F1 and B16-F10 cells. Do you have a preference about
which we should use? Does it matter?
This paper mentions something about H-2Kd Ova specificity
