警示：ElisaFake reagent kits are rampant， seven0%The above people boughttoThe ELISA kit is counterfeit（conservative estimate）

1: Claimed to be domestically produced, butProductionmanufacturerI dare not print the name on the reagent kit, it must be a fake.

2：allImport packagingYes, it's definitely fake.

Common fraud:Produce thousands at onceSame typetest kit（as：TGF-B），When you want a certain indicator, they label it with the corresponding indicator and pretend to sell it to you.TGF-β is present in most mammals (humans, rats, mice, pigs, cows)……）They are widely expressed, and the amino acid sequence homology of inter species antigens reaches 100%, TGF-The expression level of β also changes correspondingly with the influence of other factorsWhat do you want to purchaseTested indicators, counterfeitersDesign the results in advance，After receiving the reagent kit,As long as the testing process is completed,justCan obtain corresponding data.No matter what your sample is,Definitely able to produce experimental results, the standard curve is also good, and the test sample will also show colorExperimenters are easily deceived.

One:allThe imported brand ELISA does not have imported packaging, but each imported brand has its own branch in China to confirm this matter. Many salespeople from counterfeit companies actually have little understanding and boast recklessly. As long as you can name the indicators, they dare to say they have them. They don't even know that the indicators they sell don't even have corresponding antibodies or antigens from the original brand. They claim to have them. In fact, with a little effort, these types of counterfeit goods can be roughly identified before purchase.

Regarding imports, our company's years of experience can be summarized as follows:

R&DAt present, there are a total of 2464 indicators (1747 for humans, 655 for mice, 246 for rats, 33 for dogs, 26 for pigs, 13 for cats, 7 for horses, 4 for cows, 4 for cotton mice, 3 for guinea pigs, 3 for rabbits, 2 for primates, etc.). Except for humans and mice, which are relatively abundant, there are very few other species under the RD brand*

IBLThere are over 1000 indicators, but because it is difficult to check and many researchers are not clear about the specific indicators of the company, counterfeiters take advantage of this loophole and claim to be IBL imported packaging. The company has currently established an office in China, which can

UsbiologicalThere are 10000 to 20000 varieties, which are relatively comprehensive among imported brands, but the prices are relatively high. After discounting all indicators, there are few brands priced below 6000 yuan. There are six or seven total sales companies in China (you can check on your own)

Here are several methods to distinguish between genuine and fake ELISA kits:

Before purchasing:

If it is produced domestically, first ask the brand, and the counterfeiter usually says that their company produces it. So, where is the specific production address? If you say you have friends in the local area and want them to visit the production factory, the counterfeit company will use various reasons to prevent you from visiting (because they don't have a factory at all), and you can easily identify them.

(Method 2) For domestically produced products, ask if they are in stock. Counterfeit companies usually say they are in stock. The finished ELISA kit has a validity period of only 6 months, which can be verified by consulting the technical department of RD company. Unless there are special circumstances, the ELISA kit will not be in stock, and the fastest packaging time cannot be less than 24 hours (which is very efficient).

(Method 3)Purchase ELISA kitbeforeYou mustSign the contract and require the other party to affix their official seal (the contract seal has no legal effect),on the contractNote: IfWhat is soldfakereactionAt least double the payment for the reagent kit.

After purchase:

(Method 4) If someone is tempted by cheapness or does not understand the situation and buys the fake reagent kit mentioned above, *: Check if the manufacturer information is printed on the reagent kit. Fake companies dare not print their company name on the reagent kit. A few bold counterfeiters print the company name on a small piece of paper and then stick it on the reagent kit. If you purchase such a reagent kit, return it promptly. If you still don't believe it, you can verify it like this,Intentionally using2-3 piecesandTestedLet's test samples with different components together,Different samplesMeasuredSurprisingly, the values are consistent.

(Method 5) This is to further confirm that the other party has falsified, and can also serve as evidence to prove that the other party has falsified: take another test kit from the other party, cross react with the previous test kit, and if there is evidence, the other party will not dare not refuse to refund.
