Usage Cited in: BIO Web of Conferences. 2025 Jul 2.; B16F10-FLuc cells were pre-treated with/without OVA Peptide(257-264) TFA (SIINFEKL peptide) (25 nM; 2 h) and then co-cultured with OT-1 CD8⁺ T cells for 4 h. Luminescence was measured by mixing 50 μL of supernatant with 100 μL of luciferase substrate.

Descripciòn

OVA Peptide(257-264) is a class I (Kb)-restricted peptide epitope of OVA, an octameric peptide can be from ovalbumin presented by the class I MHC molecule, H-2Kb.

In Vitro

TAP1-I- and C57BL/6 macrophages may process Crl-OVA and full-length OVA in different cellular compartments and that the protein context of the OVA Peptide(257-264) epitope influences the extent of TAP-independent processing for MHC class I presentation. OVA Peptide(257-264) epitope is presented with a differential dependence on the TAP transporter depending on the protein context of the OVA epitope: OVA Peptide(257-264) contained within the MBPCrl-OVA or Crl-OVA bacterial fusion proteins is presented with little dependence on the TAP transporter, while OVA Peptide(257-264) contained within full-length ovalbumin is largely dependent on the TAP transporter, regardless of whether recombinant OVA is expressed in bacteria or the native protein is coupled to polystyrene beads^[1].

Ensayo celular

TAPl^-/- or C57BL/6 macrophages are co-incubated with either bacteria or polystyrene beads containing the 257-264 epitope from ovalbumin [OVA Peptide(257-264)], which binds the mouse class I molecule Kb. The source of the OVA(257-264) epitope is either the Crl-OVA(257-264) (Crl-OVA) fusion protein, the maltose binding protein (MBP)-Crl-OVA fusion protein, native OVA or bacterial recombinant OVA (rOVA); Crl-OVA, MBP-Crl-OVA and rOVA are each expressed in bacteria, and Crl-OVA and MBP-Crl-OVA purified from bacterial lysates and native egg OVA are coated onto polystyrene beads^[1].
