The blood collection standards have strict regulations, and the products produced by blood collection at different times are also different.

Some minor differences about fetal calf serum and his related products.

Newborn bovine serum: New born cows made blood within 5 days


Calf serum: The calf is made within 16 weeks of birth.


Fetal bovine serum

: (Imported serum) is required to take a laparotomy.


Domestic manufacturers often can't do it, and often take blood within 2 days of birth as fetal calf serum.


According to the production process of serum and the content of hemoglobin and endotoxin, it is further divided into:


(1). Special fetal bovine serum: 40

Nano

Filtration, endotoxin content ≤10EU,

Hemoglobin content ≤ 10mg / dl.


(2). Superior fetal bovine serum: after 3 times 100

Nano

filter,

Endotoxin content ≤25EU/ml,

Hemoglobin content ≤ 25mg / ml.

(3). Standard fetal bovine serum: 3 times 100

Nano

Filtration, low endotoxin,

Low hemoglobin content.


(4). Activated carbon/dextran treatment serum: The hormone content is greatly reduced.


(5). Dialysis-type fetal bovine serum: The content of hypoxanthine and thymidine is greatly reduced.

Experiments have shown that properly treated heat inactivated serum is not required for most cells. The serum treated by this treatment has only a slight promotion to the growth of the cells, or has no effect at all, even because the high temperature treatment affects the quality of the serum, and causes the growth rate of the cells.

reduce. In the heat-treated serum, the formation of precipitates is significantly increased. These precipitates are observed under an inverted microscope, such as "small black spots", which often cause researchers to mistake the serum for contamination, and put the serum at 37C. In the environment, this precipitate will be increased, which makes the researchers mistakenly believe that it is the splitting and amplification of microorganisms. Therefore we recommend that you do not need to do the heat treatment if it is not necessary. This will not only save your precious time, but also ensure the quality of your serum!

In Australia, the country of origin, the blood source is taken in a closed puncture manner.

3 times 100nm filtration, filter packaging in the purification workshop. After strict testing to ensure no mycoplasma, bacterial virus testing is in accordance with the United States Pharmacopoeia (USP) and the United States Federal Regulations ninth (9 CFR), in line with international testing standards.

Lithium Iron Series

The lithium Battery Protection Board is the charge and discharge protection for the series-connected lithium battery pack; when fully charged, it can ensure that the voltage difference between the individual cells is less than the set value (generally ±20mV), so as to realize the equal charge of each single cell of the battery pack. , effectively improving the charging effect in the series charging mode; at the same time, it detects the overvoltage, undervoltage, overcurrent, short circuit, and overtemperature status of each single cell in the battery pack to protect and prolong the battery life; undervoltage protection makes each A single-cell battery is used to avoid damage to the battery due to overdischarge.
