生物活性
OVA Peptide(257-264) acetate salt is a class I (Kb)-restricted peptide epitope of OVA, an octameric peptide from ovalbumin presented by the class I MHC molecule H-2Kb[1].
体外研究 (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].

Cell Assay
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.

生物活性
OVA Peptide (323-339) represents a T and B cell epitope of Ovalbumin (Ova), which is important in the generation and development of immediate hypersensitivity responses in BALB/c mice.
体外研究 (In Vitro)
When pulsed with 0.01 μM of OVA Peptide (323-339), M2-expressing B cells lead to an increase in the number of TH cells mobilizing calcium, compared to M2Y-expressing B cells. To assess if M2-expressing B cells are also able to promote stronger individual responses, we quantified the 405/530 ratio MFI of responding TH cells[1].

体内研究 (In Vivo)
OVA Peptide (323-339) represents a T and B cell epitope of OVA, which is important in the generation and development of immediate hypersensitivity responses in BALB/c mice. Daily aerosolization of OVA Peptide (323-339) for 20 minutes over a period of 10 days has been as effective in the stimulation of a serum anti-OVA IgE antibody response as sensitization to native OVA by the same route. After sensitization to native OVA, the majority of the IgE anti-OVA response is directed against OVA Peptide (323-339). Evaluated by hematoxylin/eosin and major basic protein immunohistochemical stainings, OVA and OVA Peptide (323-339) induce similar lung inflammation. Interestingly, significant serum total IgE and OVA-specific IgE are observed in OVA mice when compared to saline control. OVA Peptide (323-339) mice show higher serum OVA-specific IgE, OVA Peptide (323-339)-specific IgE, IL-4 and lower IFN-γ similar to OVA mice. The proliferative response to OVA is found in cultured splenocytes of both OVA and OVA Peptide (323-339) mice, while the similar proliferative response to OVA Peptide (323-339) is only observed in the splenocytes of OVA Peptide (323-339)-sensitized and challenged mice. Although OVA Peptide (323-339) induces a Th2-like response in the mouse model as does OVA, OVA Peptide (323-339) has clearly limited immunogenic potency to activate OVA-sensitized and challenged mice splenocytes, unlike OVA[2].

Cell Assay [1]
A20 B cell lines are loaded, or not, with different concentrations of OVA Peptide (323-339) overnight. Cells are then conjugated with purified mouse CD4+ T cells and incubated for 20 h. After the 20 h incubation period, supernatant is recovered and stored at -20°C. IFN-γ production is quantified in the supernatants by sandwich ELISA. 96-well plates are analyzed. T cells cultured for two to four days in the presence of 3 μg/mL of anti-CD3 antibody are used as positive control of T cell activation. B cells cultured for 48 h in the presence of 2.5 μg/mL of anti-CD40 antibody and 5 μg/mL of the F(ab’)2/F(ab) portion of an anti-mouse IgG antibody are used as positive control for B cell activation[1].

Animal Administration [2]
Mice[2] Fifty-one 8-week-old female BALB/c mice are randomly divided into three groups: OVA, OVA 323-339 and saline. They are intraperitoneally injected with 25 μg OVA or OVA Peptide (323-339) absorbed on 300 μg Alum or saline on days 0, 7, 14. On days 21-23, all groups are challenged intranasally with 20 μL of 1% OVA, 1% OVA Peptide (323-339) and saline, respectively. On days 0, 7, 14, mice are intraperitoneally injected with 25 μg OVA or OVA Peptide (323-339) absorbed on 300 μg Alum, or saline; on days 21-23, all groups are challenged intranasally with either 20 μL of 1% OVA, 1% OVA Peptide (323-339) or saline. On day 28, after killing, splenocytes are isolated and cultured under the stimulus of each allergen or medium.
