What is the serum trap on the market
Market traps of blood?
Have you ever encountered these situations:
A.Businessmen say to you, our home selling gibco is parallel, but certainly genuine, so sell very cheap.
B.Business or tell you that our home hyclone Australia is not sold before the rest, certainly authentic.
...
In fact, the vast majority of these are false. These are not genuine, nor is the parallel, that is, illegal business fraud. In fact, the serum on the fraud has formed a large industrial chain. Rumors that the laboratory usually used gibco bottle price is 50 yuan a, where these bottles go? you know.
And some businessmen to buy a large number of foreign brands for a small gibco or hyclone label on the ok, you want what batch number, how much the number, they have. The price is also a great price than the genuine discount, in fact, the pit or the user.
Maybe you will feel that you buy from some channels of the big brands of serum, cheap, So do not care. Because your cells are not so hard to imagine you, some fake serum can really raise, but the quality, stability is indeed not the same, between the large differences, even the same batch of serum are unstable, directly affect your experimental results The repeatability and the authenticity of the data.
Before the burst of a brand in the serum to add a large number of cytokines and growth factors, cells soaring, is a cell functional experiments, the results appalling. At present the brand has been banned by the United States, but this situation occurs in the country.
As for the other, such as imported serum and domestic serum 1: 1 than the right friends, serum and medium mixed friends, tricks and more to death. Everyone be careful!
In short, buy a serum, requiring a high direct look for large brands of companies or regular agents, the requirements are not particularly high, you can find some small brands of manufacturers and agents, do not buy large names of the serum, because the price is cheap, Good and stable, or the possibility of a big brand too low! We can try, the effect is good,Time lost will never come again.
Why Chinese serum does not work?
China's bovine serum quality, but off? Of course, but off, not just people, pigs and sheep of the horse and even people are not OK ah. From small to large, we eat are not safe to eat, all kinds of preservatives melamine, etc., a disease is to fight antibiotics. Do you think about the quality of the serum? A variety of antibodies, complement, including our air is also very bad. So, the source of the serum is very important, why New Zealand Australia's serum quality is very good,It goes without saying.North American serum European serum quality is also very good, followed by South America, China's quality in these is the worst.
South America, North America, Australia blood fetal bovine serum What are the differences?
In fact, the quality of serum in North America and Australia is about the same. This is the conclusion after the practice? Some people say gibco 10099-141 good quality, it was also said 16000-044 good quality, in fact, the blood source I think the quality of Australia and New Zealand will be better, but on the manufacturing process, I personally think that the United States will be better, The result of the synthesis is that the overall quality will be better. Why is the price of Australian serum so high? Because the North American serum is China's restricted imports, so China can only import regular serum from Australia, so that the Australian serum goods in short supply. Now the price of Australian serum is more than 3,000 yuan, the purchase price of the first hand, the terminal price of 4500 or so, you may say that business is so black. Haha this is a normal profit margins. So if someone told you that he sold the original Australian serum less than 3000, then there is a problem. Own to distinguish.
South American serum is more complex, and now the South American serum because of cheap by many customers love. What is the beauty of the South American serum? Quality domestic blood posing as imported from South American serum, South America and domestic against the serum. General customer-friendly cell lines will use the South American serum, so buy posing high imitation and other poor quality of the serum, then in fact raise up the problem is not big. But, but, but the important thing to say three times, the stability is poor, with the use of to die.
How to identify high imitation serum?
Many customers buy very red South American serum call me, why is this red blood? I asked: what is the serum buy? Answer: South America. South American serum itself is very red and red, blood red, I have seen many companies in South America is very red serum, South America in addition to Argentina, are very red, and heme does not affect the quality of serum. But I said above a lot of imitation goods is not red, which is a problem. If a customer now also said that why the South American serum so red, I think he bought authentic South American serum over it? Domestic serum is waxy yellow, wax yellow is what color? You can go to Google search. North American serum color is not so red color is very light, pale yellow to reddish. Australian serum is between South America and North America.
