Background technology
Alzheimer syndrome is called alzheimer's disease, its main feature is that sick man memory and cognitive ability are gradually lost
It loses.Patient is dead in 3 to 9 years after making a definite diagnosis, and accounts for 50% to the 56% of clinically dead case.The current understanding of the disease cause of disease is big
The beta- amyloid proteins folded extremely and Tau albumen of intracerebral accumulation result in alzheimer's disease.
The drug of alzheimer's disease currently on the market is mainly Western medicine, it is characterized in that must adhere to taking for a long time, however
But curative effect is small, can only alleviate partial symptoms, it is impossible to control the development of the state of an illness.Another defect taken for a long time is drug pair
Effect is big, while patient generates drug dependence.It is badly in need of better efficacy, the lower drug of side effect in the market thus.
Current recent studies have shown that:Recognizing for old mouse can be promoted to the blood plasma of old mouse continuous injection youth mouse
Know level (Villeda S.A.Young blood reverses age-related impairments in cognitive
function and synaptic plasticity in mice.Nature Medicine 2014;20:659-663).For
This, can may effectively promote the human-subject test of Alzheimer's containing Cucumber in blood plasma.But these substances
Concrete component and separation acquisition methods have not been reported.

Embodiment 1:The preparation of mixture
(1) it takes a blood sample from adult mice, collects blood plasma
By 100 adult C75BL/6 strains mouse (mouse can also use other strain experimental animals replace,
Such as:The mouse of BALB/cA strains, the mouse of DBA/2 strains, SD rats, Wistar rats) with the carbon dioxide of 20vol%
(gas that i.e. carbon dioxide content is 20vol%) anesthesia, then with blood taking needle from mice eye bloodletting to heparin tube (heparin tube
For anticoagulant tube) in, heparin tube is rocked in bloodletting, prevents blood clotting.Heparin tube containing blood is put into centrifuge, is set
Rotating speed is 1000g, is centrifuged 30 minutes.Then supernatant is carefully drawn with pipettor, the blood plasma being as collected into.
(2) cocktail component mixture i.e. of the invention is isolated from mice plasma
(a) density gradient centrifugation
Blood plasma is subjected to density gradient centrifugation first:12 milliliters of addition is a concentration of in the centrifuge tube that total volume is 13 milliliters
Then 50% Percoll adds 1 milliliter of mice plasma;Centrifuge tube is put into ultracentrifuge, setting speed is
12000g, set temperature are 4 degrees Celsius, centrifuge 5 hours.After density gradient centrifugation, removed with pipettor most upper in centrifuge tube
Layer RED sector, plasma component remaining in centrifuge tube is dialysed together with Percoll.
(b) it dialyses
General bag filter is selected in dialysis, and bag filter aperture is about 0.25 nanometer.The blood that will be obtained after density gradient centrifugation
Slurry component is added in bag filter together together with Percoll, then bag filter is put into the beaker of 1L, in beaker outside bag filter
The 1mM Tris hydrochloride buffers (pH8.0) of 1L are added in, are dialysed while stirring.Temperature of dialysing is 4 DEG C, and dialysis time is small for 24
When.After dialysis, using the remaining plasma component in bag filter as dialysis product, pending primary concentration.
(c) primary concentration
Plasma component after dialysis is added in the concentration tube that volume is 2 milliliters, concentration tube allows size to be 2,000 dongles
The substance to pause passes through.Concentration tube is put into centrifuge, setting speed 3000g, set temperature is 4 DEG C, starts centrifuge, opens
Begin to concentrate, until final volume is 500 microlitres.Later, the blood plasma after remaining dialysis is added in again in the centrifuge tube so that
The volume of plasma component reaches 2mL, is centrifuged with identical parameter, and it is 500 microlitres to be again concentrated to final volume.So follow
Ring concentrates, and is 500 microlitres until the plasma component after dialysing finally is concentrated to volume.Using 500 microlitres of plasma components as
One concentration product is denoted as plasma component A, pending that high kurtosis albumen is gone to handle.
(d) high kurtosis albumen is removed
High kurtosis albumen is gone to remove high kurtosis protein reagent box using the model 163-3006 of BIO-RAD companies production,
Obtained after concentration 500 microlitres of blood plasma are added in the pillar of high kurtosis albumen, then which is put into 4 DEG C of ice
Case places 5 hours.2 milliliters of dcq buffer liquid is added in into pillar later, 4 degrees Celsius centrifuge 5 minutes, and centrifugal rotational speed is
10000g.Then 500 microlitres of elution buffer is added in into pillar again, 4 DEG C are placed 30 minutes, are then centrifuged 5 minutes for 4 DEG C,
Centrifugal rotational speed is 10000g, and the plasma component eluted later is to go the plasma component after high kurtosis albumen, is denoted as blood plasma
The for use anion-exchange columns of plasma component B are further purified component B.
