Detection kits Proteins Background

The detection kit is a box for containing chemical reagents such as chemical components, drug residues, and virus species.

Figure 1. The composition of Detection kits.

The complete ELISA kit contains the following components:

(1) A solid phase carrier (immunoadsorbent) that has been coated with an antigen or an antibody;

(2) An enzyme-labeled antigen or antibody (conjugate);

(3) A substrate for the enzyme;

(4) Negative control and positive control (in qualitative determination), reference standard and control serum (quantitative determination);

(5) A dilution of the combination and the specimen;

(6) Washing solution, in the plate ELISA, the commonly used diluent is 0.05% Tween 20 phosphate buffered saline;

(7) Enzymatic reaction stop solution, the commonly used HRP reaction stop solution is sulfuric acid, and the concentration thereof varies depending on the amount of addition and the final volume of the colorimetric solution, and is generally 3 mol/L in the plate ELISA.

Kit contents (taking a centrifugal column as an example):

1. Generally included: lysate RL

2. Deproteinized solution RW1

3. Rinse RW

4. RNase free ddH2O

5. Adsorption column (RNase free)

6. Filter column (RNase free)

7. Buffer

8. Centrifuge tube (RNase free)

9. Collection tube (RNase free)

In addition, there is a kit instruction manual, depending on the manufacturer, may also be equipped with different reagents, such as: DNase, lysozyme.

When using, you must purchase a special extraction kit according to your own experimental needs. If it is not a special kit, you may be able to propose RNA, but it cannot ensure the quality and integrity, which will affect RT-PCR, Northern blot, Dot blot, Real time RT. Results of subsequent experiments such as PCR, microarray analysis, polyA screening, in vitro translation, RNase protection analysis, and molecular cloning.

The current extraction effect is good by the RNA extraction kit produced by QIANGEN, but its price is high, the cost of a single experiment is too high, and there is no need to purchase the experiment with low precision. Of course, there are other imported kits. However, there are problems of high price and long ordering period (if it is not domestically available, it will be shipped from abroad for a long time). Ordinary extraction experiments with domestic kits are sufficient, the price is not high, basically all local stock, such as Tiangen (currently produced in the domestic production of a relatively wide range of kits), etc., its price than imported kits It's much cheaper, and the effect is not bad, the price is OK.

Of course, in terms of RNA extraction, the extraction effect of the kit is not necessarily very good. In fact, some classical RNA extraction methods are used, and the effect is also very good, such as: TRIZOL, EDTA, etc., but the kit is easy to use, the classic method. The operation is more complicated.
