Description

S-100 chemiluminescence immune detection reagent kits and preparation method thereof
Technical field
The present invention relates to vitro detection field, more particularly to a kind of S-100 chemiluminescence immune detection reagent kits and its system Preparation Method.
Background technology
People's S-100 albumen is concentrated mainly in the astroglia of central nervous system and corresponding tumour cell, point Son amount is relatively low, belongs to one group of acid calbindin, because this material is soluble in the saturated ammonium sulfate solution of pH=7, Therefore it is referred to as S-100 albumen.S-100 is most activated member in central nervous system, mainly prosperous in the snow of nervous system In Schwann Cells and Deiter's cells, at the same exist in Langerhans cell, cartilage cell, adrenal gland satellite cell and In the Non nervous systems such as melanic cell.
At present, clinic detects that discriminating tumour originates from using S-100 protein monoclonal antibodies to clinical samples, Improve diagnosis of glioma correctness.The distribution of S-100 albumen is relatively broad, is currently used primarily in central nerve neuroma Antidiastole, S-100 can as differentiate tumour be whether ectodermal origin important indicator.To in 95 astrocytomas The expression of S-100 albumen is analyzed, and as a result shows that S-100 Protein Subtypes have expression in astrocytoma, and Its expression is with malignancy in negative correlation.
At present the common methods of clinical detection people's S-100 albumen have enzyme linked immunosorbent assay, radio immunoassay, enzyme Promote chemoluminescence method, but these methods all have some shortcomings part.
First, enzyme linked immunosorbent assay
Enzyme linked immunosorbent assay (ELISA) is widely used, but the method there is also following weak points:
(1) using 12 × 8 types, 6 × 8 types, 8 × 12 types or the hole Special micro porous plate of complete plate 96 as antigen coat apparatus and anti- Container is answered, 12 batches, 6 batches, 8 batches or whole plate first use can only be divided into when in use, it is impossible to carried out independent, single The detection of person-portion;
(2) reagent type used by quantitative determining is more, and each detection reagent will be contained with reagent bottle, and often be made It is required for changing imbibition nozzle to be filled into respectively in the micropore of microwell plate during with a kind of reagent, not only reagent bottle species is more, filling The operation of reagent is also extremely loaded down with trivial details;
(3) lack the corresponding mark to detection information, can only just will appreciate that by checking the mark of kit external packing box or know The product batch number and term of validity information of detection reagent are known, and the information known is uncontrolled in detection process, with very big Randomness;
(4) detection reagent easily causes the cross pollution between various reagents and shadow in open space in detection process Ring the accuracy of testing result;
(5) dosage more than detection process using manual operations, reagent or sample is not bery accurate, and operating process is extremely loaded down with trivial details and multiple It is miscellaneous, bust is susceptible to, the degree of accuracy of testing result and precision are poor;
(6) item number × 48/96 person-portion is in the quantity configuration of detection project reagent set and using on, if necessary to examine 10 projects are surveyed, then the configuration of reagent and the use of number must be 10 × 48/96 person-portions, if only a sample needs detection 10 Individual different project, it is also desirable to configure the reagent of 10 × 48/96 person-portions, haves the shortcomings that inadequate economical rationality.
2nd, radio immunoassay

Taking pooled serum and adding chaff interference respectively includes:Combined with bilirubin, unconjugated bilirubin, hemoglobin, ascorbic acid, glycerine Ester, adding proportion is according to 1:20 are carried out, and are determined pooled serum respectively and be with the addition of the measured value of pooled serum after various chaff interferences, Deviation therebetween is calculated, with ± 10% as tolerance interval.As a result show, interference reaches the files-designated of NCCLS Standard, can be used for the accurate evaluation of clinical labororatory's S-100 situations.
The contrast experiment of embodiment 4, S-100 chemiluminescence immune detection reagent kits
It is respectively 0 μ g/L, 0.01 μ g/L, 0.2 μ g/ to concentration with chemical luminescence detection method and traditional enzyme linked immunosorbent assay The S-100 samples of L, 3 μ g/L, 10 μ g/L and 40 μ g/L detect that two methods detection sensitivity is compared, data such as following table institute Show:
As can be seen from the above table, the sensitivity of chemical luminescence detection method improves about 20 times compared with enzyme linked immunosorbent assay.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more concrete and detailed, but can not Therefore it is interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, Without departing from the inventive concept of the premise, some deformations and improvement can also be made, these belong to the protection model of the present invention Enclose.Therefore, the protection domain of patent of the present invention should be defined by claims.
