The recommended dilution factor for different samples is as follows (for reference only):
| Sample Type | Dilution Factor |
|---|---|
| 10% Mouse liver tissue homogenate | 1 |
| 10% Rat brain tissue homogenate | 1 |
| 10% Rat kidney tissue homogenate | 3-5 |
| 10% Rat liver tissue homogenate | 1-3 |
| 10% Rat heart tissue homogenate | 1 |
| Human serum | 1 |
The diluent is normal saline (0.9% NaCl) or PBS (0.01 M, pH 7.4). For the dilution of other sample types, please do pretest to confirm the dilution factor.
