As we all know, urokinase is a natural drug for the prevention and
treatment of cerebral thrombosis, which can only be used for intra-cardiac
injection and intravenous injection. When it comes to the extraction method of
urokinase, it is estimated that everyone is not very clear. Today, we will
follow the urokinase manufacturer to understand that the raw material of
urokinase must be urine. Some schools now place plastic buckets in the boys'
bathrooms to collect boys' urine, which is then distilled and sold to
pharmaceutical companies for use in the production of urokinase. Experts say the
samples are relatively healthy because the students are young, and the specific
conditions of the samples need to be verified by professional organizations.
Let's learn about the extraction method of urokinase.
Step 1: Collect the specimen. After filling the plastic bucket with urine,
store it in a cool place.
Step 2: The PH value of urine should be adjusted below 6.5. Special
attention should be paid to the fact that samples are easy to deteriorate in
summer, and phenol should be added to urine specimens to prevent
Step 3: Each collection of specimens must be processed within 8 hours.
The fourth step: the specimen shall be precipitated. The temperature of the
specimen shall be kept below 10 degrees Celsius, and then the PH value shall be
adjusted to 8.5 after using sodium hydroxide. The two shall be stirred evenly
and left for one hour, and the supernatant shall be extracted with a rubber tube
after precipitation. At this point the PH will acidify to around 5-5.5.
Step 5: Add the acidified urine in proportion to the pre-treated diatomite
Step 6: Wash the diatomite adsorbent with cold water (5 degrees Celsius is
appropriate). When the water from the diatomite column drips out from the clear
and muddy, the collection of urokinase can begin.
