Product Description
OVA Peptide(257-264) TFA is the class I (Kb)-restricted peptide epitope of OVA, which is an octamer peptide that can be developed from ovalbumin presented by the class I MHC molecule H-2Kb.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
TAP1-I- and C57BL/6 macrophages can process Crl-OVA and full-length OVA in distinct cellular compartments. Additionally, TAP-independent processing of MHC class I presentation is influenced by the protein background of the OVA epitope, OVA peptide (257-264). The TAP transporter presents the epitope in several ways: While the OVA peptide (257–264) in full-length ovalbumin is highly dependent on the TAP transporter, regardless of whether the native protein is coupled to polystyrene or the recombinant OVA is expressed in bacteria, the OVA peptide (257–264) in the MBPCrl-OVA or Crl-OVA bacterial fusion protein depends on the TAP transporter [1].

Solubility Data
Solubility (In Vitro)
DMSO : ~125 mg/mL (~116.05 mM)
H2O : ~50 mg/mL (~46.42 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.08 mg/mL (1.93 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 0.8395 mL 4.1975 mL 8.3950 mL
5 mM 0.1679 mL 0.8395 mL 1.6790 mL
10 mM 0.0840 mL 0.4198 mL 0.8395 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
