" SSNA1 autoantibody " herein refers to " SSNA1 albumen autoantibody ".
Detailed description of the invention
Fig. 1: SSNA1 autoantibody comparison in patients with lung cancer (LC), normal healthy controls (NC) serum slurry.
Fig. 2: patients with lung cancer (LC) and normal healthy controls (NC) ROC are analyzed.
Specific embodiment
The relationship of SSNA1 autoantibody and lung cancer in 1 blood plasma of embodiment
One, clinical data
Patients with lung cancer 30 are chosen, normal healthy controls 30, essential information is as follows:
| Essential information | Patients with lung cancer | Normal healthy controls |
| Number | 30 | 30 |
| Age | 58±10.5 | 42±8.9 |
| Masculinity proportion | 20 (66.7%) | 13 (46.7%) |
Two, testing principle
HuProtTMBe fixed with SSNA1 albumen on human protein's custom chip, after increase serum is incubated for, in serum SSNA1 from
Body antibody (including mainly IgG, IgM type antibody, there are also other types of antibody) can be in conjunction with up, and cleaning removal is unbonded
Antibody and other oroteins, then with anti-human IgM fluorescent marker secondary antibody (cy5 mark, present red) and anti-human igg fluorescence secondary antibody
(cy3 label, green is presented) detection reads signal, the power and the affinity and quantity of antibody of signal by Fluorescence Scanner
It is positively correlated.
Three, method
Reagent used in this part is as follows:
Specific step is as follows:
1) rewarming: chip is taken out from -80 DEG C of refrigerators, 4 DEG C of refrigerator rewarming half an hour is placed in, is subsequently placed in room temperature rewarming
15min；
2) close: the chip after rewarming fixes 14 blocks fences, and after fixing, envelope is added into each block
Liquid is closed, and is placed on side-sway shaking table, room temperature closes 3hr；
3) serum sample is incubated for: after the completion of closing, then confining liquid to the greatest extent is rapidly added preprepared serum and is incubated for
Liquid, every chip can be incubated for 14 serum samples, and the loading volume of each serum sample is 200 μ L, side-sway shaking table 20rpm, and 4 DEG C
It is incubated overnight (serum sample is firstly placed on 4 DEG C of chromatography cabinet freeze thawing, adds Incubating Solution with 1:50 dilution proportion, obtains serum Incubating Solution)；
4) it cleans: chip and chip fence being taken out together, suck sample, is then rapidly added isometric PBST, such as
This circulation for several times, guarantees when removing chip fence no cross contamination between serum sample.After removing chip fence, chip is placed in
Added with the chip cleaning box of cleaning solution, horizontal shaker, room temperature 80rpm is cleaned 3 times, each 10min；
5) secondary antibody is incubated for: chip being transferred in the incubation box that joined 3mL secondary antibody Incubating Solution, side-sway shaking table 40rpm is kept away
Light, room temperature 1hr；
6) it cleans: chip being taken out into (upper surface for paying attention to touch or scratching chip), is placed in the core added with cleaning solution
Piece cleaning box, horizontal shaker, room temperature 80rpm are cleaned 3 times, each 10min.It is cleaned 2 times with ddH2O after the completion, each 10min；
7) dry；
8) it scans: being scanned using brilliant core LuxScan 10K micro-array chip scanner；
9) data are extracted: corresponding GAL file (having recorded albumen position in chip) is opened, by chip image and
The each array of GAL file is integrally aligned, and presses automatic aligning button, is extracted data and is saved.
Four, result
The Average expression level of SSNA1 autoantibody in Plasma of The Patients With Lung Cancer is 23.3SNR (fluorescence signal relative quantification
Ratio), the Average expression level of SSNA1 autoantibody is 31.9SNR in normal healthy controls blood plasma.Lung cancer group and healthy control group (p
< 0.01) statistically significant (Fig. 1) is compared.It is 86.7% that the ROC of lung cancer group and normal healthy controls, which analyzes result specificity, quick
Perception is 26.7% (Fig. 2), shows that SSNA1 autoantibody can specifically distinguish lung cancer and normal healthy controls.
It can be seen from the above result that the level difference of SSNA1 autoantibody is aobvious in patients with lung cancer and the serum of non-lung cancer patient
It writes, by the level of SSNA1 autoantibody in detection serum, can achieve the purpose that screening lung cancer.
The composition and its application method of the detection kit of the invention of embodiment 2
One, kit forms
Detection kit (14 person-portion):
Two, kit application method
With 1 Part III of embodiment --- " detection of SSNA1 autoantibody in serum ".
Kit of the invention can be by the level of SSNA1 autoantibody in detection serum, can be with screening crowd to be checked
Suffer from the risk of lung cancer: if SSNA1 autoantibody is low (for Healthy People), the risk for suffering from lung cancer is high, if SSNA1
Autoantibody is high, then the risk for suffering from lung cancer is low.It can be used for the auxiliary diagnosis of clinical lung cancer, take relevant treatment for patient
Measure or decision provide effective foundation, and potential applicability in clinical practice is good.
