Description
Technical field
The present invention relates to a kind of biotinylation kits, method and its application, detect simultaneously more particularly to one kind more in blood plasma
The kit of kind component content, method and its application, belong to field of biotechnology.
Background technique
Acute abdomen (acuteabdominalpain) is one of most common illness of Emergency Patients, is gone to a doctor whole year
Occur, peak is autumn (9~November) and summer (6~August) respectively, and the medical age concentrates between 15~44 years old (accounting for medical
The 72.7% of sum), often it is related to the disease of inside and outside, youngster, even neural, the spiritual each section of woman's production, Etiological is abdominal viscera
Organ occurs caused by lesion, structure malfunction, the outer adjacent organs damage of abdomen or systemic disease.According to statistics, non-wound impatient
The disease incidence highest of acute pancreatitis, followed by acute gastroenteritis, acute ileus, acute appendicitis, urgency in disease abdominal pain disease
Property cholangitis, ulcer acute perforation etc..Such disease often has the characteristics that morbidity is anxious, variation is fast, the state of an illness is complicated and serious, adds
It, Hospitals at Present emergency department clinician tends to rejuvenation, and experience is insufficient in terms of emergency diagnosis, is easy to diagnose wrong or treatment
Improperly, it may cause adverse consequences in this way, or even dead.Therefore, more demanding to the diagnosis of acute abdomen, it can make in time
Specific diagnosis, is reasonably treated, will directly affect the treatment and prognosis of disease.For this phenomenon, the present invention is proposed
By Trypsinogen-2 in serum (TPS II), serum amyloid A protein (SSA), hs-CRP (hs-CRP), calcitonin
The acute abdomen that former (PCT) and phylaxin carry out joint-detection checks scheme, corresponding detection kit is developed, to acute abdomen
Common acute pancreatitis, acute appendicitis, acute peritonitis, acute gastroenteritis are excluded with exedens acute perforation.
Currently, the external context of detection in clinical acute disease abdominal pain, mainly by combining patient medical history, carry out a medical examination,
Laboratory auxiliary examination selectively carries out blood glucose, pregnancy tests, blood electrolyte, hepatic and renal function, abdominal CT according to conditions of patients
Inspection, abdominal cavity diagnostic puncture and ascites analysis etc. check, and then comprehensively consider, propose corresponding therapeutic scheme.This
Outside, the investigation of acute pancreatitis is also carried out, but for acute disease abdomen using the detection to acute abdomen Urinary Trypsinogen-2
Report of the investigation of bitterly relevant other diseases still without relevant biomarkers object.At home, the clinic of acute abdomen is examined
Survey is similar to external clinical detection, but application development of the TPS II in external clinical diagnosis is more early, and is at home nearly 2 years lands
Continuous just to start to enter into clinical application in Grade III Class A hospital, its clinical value is still in further exploration.This
Invention is by carrying out joint quantitative detection with phylaxin to TPS II, SSA, hs-CRP, PCT in acute abdomen patients serum, to urgency
Disease abdominal pain common disease is checked, and is made reasonable diagnosis in time for clinician and is provided auxiliary tool.
Summary of the invention
The main object of the present invention be solve the related disease of acute abdomen in the prior art investigation sensitivity it is low, accurate
Property difference and cumbersome and inconvenient problem, and provide kit that is a kind of while detecting Multiple components content in blood plasma.
The purpose of the present invention can reach by using following technical solution:
Kit that is a kind of while detecting Multiple components content in blood plasma, including detection solution R1, detection solution R2, antibiosis
Object positive markers quality controlled serum and antibiont marker negative quality controlled serum.

Any one in ball.
Biomarker antibody is monoclonal antibody, and monoclonal antibody passes through monoclonal hybridoma technology and prepares
It obtains or is obtained by phage antibody technology screening.
Sensitizing latex is prepared especially by following method:
Step 1: latex activation
Latex is added in suitable MES buffer, after ultrasonication, is slowly added to thereto under stirring conditions
EDA and NHS, constant-temperature incubation for a period of time after, centrifugation, remove supernatant, then PBS buffer solution is added into precipitating, carry out ultrasonication,
Repeat 1 time from addition PBS to the step of progress ultrasonication, obtains latex particle;
Step 2: antibody linked
PBS is added into latex particle, after carrying out ultrasonication, the monoclonal for being separately added into biomarker thereto is anti-
Body, additional amount is 1.5~6mg/ml, after mixing, is placed in be incubated at room temperature to reaction solution and is evenly distributed state, sensitizing latex;
Step 3: closing
The glycine for being 3.3%mg/ml with PBS buffer solution compound concentration, by glycine solution and sensitizing latex according to body
Product is mixed than 100:5, and after ultrasonication, 40~50min is incubated at 25 DEG C, and pH7.5,50mM are then added thereto and includes
The PBS buffer solution of 0.05wt%BSA after mixing, is incubated overnight at 25 DEG C;After centrifugation, PBS, ultrasonication are added thereto;From
The heart removes supernatant, and 0.05% tween is added, is centrifuged again after ultrasonication, removes supernatant, after 0.05% BSA is added, surpassed
After sound is broken, the stabilizer Proclin300 of 0.05% BSA and 0.1% is continuously added, carries out ultrasonication, ultrasonication
Condition is 100Hz, 0.8s/ times, carries out 2min altogether, is then saved for use for 4 DEG C.
Biomarker positive quality control serum and the biomarker feminine gender quality controlled serum are all normal human serums, biology
Positive markers quality controlled serum is by adding TPS II, SSA, hs-CRP, PCT and phylaxin mark respectively in normal human serum
Quasi- product are made, and additive amount is 3 times of the critical value of TPS II in normal serum, SSA, hs-CRP, PCT and resistance cellulose content.
Kit includes the detection cup of five kinds of different colours label, respectively to TPS II in serum, SSA, hs-CRP, PCT and
The detection of phylaxin, the range of linearity of detection are followed successively by 2.5 μ g/L of μ g/L~1250,0.1ng/ml~300ng/ml, 0.3mg/L
~150mg/L, 0.1ng/ml~250ng/ml, 1ng/ml~200ng/ml.
Method that is a kind of while detecting Multiple components content in blood plasma, includes the following steps:
By the way that the corresponding antibodies of substance to be checked are coupled with latex particle, by the specific bond of antigen and antibody,
So that latex particle is aggregated, changes the turbidity of antigen-antibody reaction system, improve the sensitivity of detection;
By the joint-detection of serum T PS II and hs-CRP, Acute Pancreatitis with Acute is checked, joint-detection serum is passed through
The content of middle PCT and hs-CRP, diagnosis investigation that is timely, effectively completing acute peritonitis, facilitates the observation of clinical efficacy;
By the joint-detection of serum SSA and hs-CRP, acute appendicitis is checked, by being supported in patients serum
Exedens acute perforation is checked in the detection of anti-element and the content of hs-CRP into property;
The serum sample that will be obtained after TPS II, SSA, hs-CRP, PCT and phylaxin standard items or the centrifugation of EDTA anticoagulated blood
This is mixed with the prepared sensitizing latex containing corresponding antibodies respectively, reacts antigen-antibody sufficiently, to antigen-antibody
After reacting a period of time, with the absorbance of full automatic biochemical apparatus measurement reaction solution, reference standard curve can determine detection respectively
The content of TPS II, SSA, hs-CRP, PCT and phylaxin in sample.
It is related to be used to prepare investigation acute abdomen for application that is a kind of while detecting the kit of Multiple components content in blood plasma
On the reagent of disease, acute abdomen related disease is acute pancreatitis, acute peritonitis, Peptic Ulcer with Acute Perforation, acute
Any one in ecphyaditis and septicemia.
Advantageous effects of the invention:
