| Description | Influenza Hemagglutinin (HA) Peptide is a tag peptide derived from an epitope of the influenza hemagglutinin protein. |
| In vitro | HA Peptide, derived from human influenza hemagglutinin (HA) amino acids 98–106, is a potent epitope widely utilized for isolating, purifying, detecting, and tracking proteins of interest due to its strong immunoreactivity. It is commonly employed in the separation of tagged proteins from cell culture supernatants and lysates at neutral pH, making it a valuable tool for coimmunoprecipitation and detection via western blotting. Given its small size, HA Peptide minimally impacts the biological activity and functionality of fusion partner proteins. The purification of recombinant HA-tagged proteins is facilitated by a highly specific anti-HA monoclonal antibody immobilized on resin, allowing for separation. These proteins can be eluted using a gentle method with an HA epitope at 1 mg/mL in TBS or through one of the three chemical elutions: 0.1 M glycine (pH 2-2.8), 3 M NaSCN, or 50 mM NaOH. Additionally, incorporating an N-terminal HA Peptide into mammalian expression vectors is crucial for T7 promoter-driven expression in E. coli, independent of trans-acting T7 RNAP. However, research indicates that caspase 3/7-mediated cleavage of HA Peptide abolishes its immunoreactivity, cautioning against its use in studying cell death and apoptotic mechanisms due to potential artifacts. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
