Endotoxin in human peripheral blood lymphocyte isolate
Product Description
Product introduction：
It is mainly used for the isolation of human peripheral blood lymphocytes
Matters needing attention：
1. operate under sterile conditions and store at room temperature after sealing. 2. samples, reagents and experimental environment in the whole process shall be carried out at 20 ± 2 ℃. In order to obtain the best experimental results, it is best to carry out the experiment within 2 h after taking blood. The longer the blood is stored, the worse the cell separation effect is. After the blood is placed for more than 6h, the separation effect is worse or even can not achieve the purpose of separation. 3. in this experiment, it is better not to use plastic products with high polymerization materials (such as polystyrene), but use non-static, low static ionization heart tubes and glass products without alkali treatment, because the electrostatic effect will lead to cell adhesion, and the surface of alkali treated glass will become rough, which will affect the effect of cell separation. 4. aspirating too many lymphocyte layers and separation liquid layers will cause the granulocytes at the junction of separation liquid to be aspirated, thus increasing the number of mixed granulocytes. 5. absorbing too much upper layer solution of lymphocyte layer will lead to the mixing of plasma proteins and platelets. 6. when the blood sample viscosity is too high and needs to be diluted, the optimal dilution method is: dilute and mix the blood and sample diluent (product No.: h9044) 1:1 for standby. Note: improper dilution method will reduce cell yield and activity. If the blood sample is diluted, the centrifugal force and centrifugation time should be appropriately reduced during the separation process. 7. due to the individual differences of blood samples and different blood viscosity, the centrifugal force and centrifugal time should be adjusted. The maximum centrifugal force should not exceed 1000 g.
