Description
(1) technical field
It the utility model is related to a kind of bladder chalone C time-resolved fluorescence detection card and kit.
(2) background technology
Bladder chalone C (cystatin c) is a kind of cystatin, also referred to as γ-trace of albumin and
γ-postglobulin, is widely present in the karyocyte and body fluid of various tissues, is a kind of low molecular weight, alkaline both the non-glycated egg
White matter, molecular weight 13.3KD, is made of 122 amino acid residues, can be produced by all karyocytes of body, generation rate is permanent
It is fixed.Bladder chalone C in circulation is only eliminated through glomerular filtration, is a kind of endogenous mark for reflecting glomerular filtration rate(GFR change
Will thing, and in proximal convoluted tubule reabsorption, but blood is not returned to by complete metabolic breakdown after reabsorption, therefore, its blood level by
Glomerular filtration determines, and does not depend on any foeign element, is a kind of reflection glomerulus filter such as gender, the influence at age, diet
Cross the preferable homology marker of rate change.
Under normal circumstances, concentration of the CysC in serum and blood plasma is 0.51-1.09mg/L (term of reference).Work as renal function
When impaired, the concentration of CysC in blood changes and changes with glomerular filtration rate(GFR.During renal failure, glomerular filtration rate(GFR declines,
Concentration can increase more than 10 times to CysC in blood；If glomerular filtration rate(GFR is normal, and when renal tubular function is not normal, CysC can be hindered
Absorb in renal tubule and decompose rapidly, the concentration in urine is increased more than 100 times.Research data is it has been shown that CysC is compared with serum
BUN, Cr have the Sensitivity and Specificity of higher, have very important value for evaluation glomerular filtration rate(GFR, CysC is so far
Substantially meet the endogenous material of preferable endogenous GFR marker requirements.It is the one kind for the assessment renal function that newly-developed gets up
The index that sensitiveness is good, specificity is high.
The method for measuring bladder chalone C in the prior art mainly has immunoturbidimetry, fluorescence immune chromatography method, colloidal gold method
Deng.Wherein colloidal gold method has the advantages that easy to operate quick, but sensitivity is low and quantitative inaccurate；Immunoturbidimetry is more quick
It is sense, accurate, full automatic biochemical apparatus is can be applied to, but instrument and time-consuming longer is needed, it is adapted to processing great amount of samples, can not meets fast
The purpose of speed detection；Immunofluorescence technique is that bladder chalone C antibody is covalently bonded on fluorescent microsphere surface active groups, by swashing
Whether detection line produces fluorescence and carrys out judging result after hair, rapid and convenient can accurate quantitative analysis have the high sensitivity, label steady at the same time
The advantages that determining, in medical immunology detection field extensive use.
But many compounds and albumen in biofluid and serum can inherently fluoresce, therefore use tradition
Fluorescein when chromophore carries out fluoroscopic examination sensitivity will degradation, but most of background fluorescence signal is to deposit in short-term
, come labelled antibody or antigen as label using rare-earth fluorescent microballoon (lanthanide chelate).Because of lanthanide series
Chelate stoke displacements are easy to differentiate exciting light greatly and launch light, so that exciting light interference is excluded, and decay time length can lead to
Cross time resolution and eliminate background fluorescence interference, in addition lanthanide chelate exciting light spectrum width and emission spectrum is narrow further to carry
High sensitivity and reduction background fluorescence.Therefore time-resolved fluoroimmunoassay technology, while two ginsengs of Detection wavelength and time are used
Number carries out signal resolution, can effectively exclude the interference of non-specific fluorescence, drastically increase sensitivity for analysis.
