| Problem | Possible Causes | Solution |
| 洗脱液中的HA标签蛋白太少甚至没有 | Protein is not completely eluted. | Change elution methods. |
| No target protein expressed. | Make sure the protein of interest contains the HA-tag by Western blot or dot blot analyses. | |
| Very low protein expression level. | 1.Use larger volume of cell lysate. 2.Optimize expression conditions to raise the protein expression level. | |
| Washes are too stringent. | Reduce the time and number of washes. | |
| Incubation times are inadequate. | Increase the incubation time. | |
| Interfering substance is present in sample. | Lysates containing high concentration of DTT,2-mercaptoethanol,or other reducing agents may destroy antibody function,and must be avoided. | |
| Detection system is inadequate. | If Western blot detection is used: 1.Check primary and secondary antibodies using proper controls to confirm binding and reactivity. 2.Verify that the transfer was adequate by using prestained protein marker or staining the membrane with Ponceau S. 3.Use fresh detection substrate or try a different detection system. | |
| 背景太高 | Proteins bind nonspecifically to the Anti-HA monoclonal antibody,insufficient washing on magnetic beads,or the microcentrifuge tubes. | 1.Pre-clear lysate with Mouse IgG Magnetic Beads to remove nonspecific binding proteins. 2.After suspending beads for the final wash,transfer entire sample to a clean microcentrifuge tube before centrifugation. |
| Washes are insufficient. | 1.Increase the number of washes. 2.Prolong duration of the washes,incubating each wash for at least 15minutes. 3.Increase the salt and/or detergent concentrations in the wash solutions. 4.Centrifuge at lower speed to avoid nonspecific trapping of denatured proteins. | |
| 洗脱液中出现多个蛋白条带 | The protein is not stable at room temperature. | Purify the target protein at lower temperature,such as 4℃. |
| Protein degradation due to proteases activity during purification process. | Add protease inhibitors to cell lysate. | |
| Non‐specific binding. | 1.Prepare cell lysate again. 2.Add additional wash steps. |
