Linear Ntau: 1.00 ~ 40.00 pmol / L;
Kab rov tav coefficient R ≥ 0.990;
Precision: hauv batch CV yog ≤ 15%;nruab nrab ntawm pawg CV yog ≤ 20%;
Qhov tseeb: qhov sib txawv ntawm qhov ntsuas qhov ntsuas yuav tsum tsis pub tshaj ± 15% thaum ntsuas qhov ntsuas qhov tseeb ntawm tus qauv.
1. Khaws lub ntes tsis nyob ntawm 2 ~ 30 ℃.Qhov tsis yog ruaj khov mus txog 18 lub hlis.
2. Khaws Anbio G17 Rapid Quantitative Test Cartridge ntawm 4 ~ 30 ℃, txee lub neej yog txog 18 lub hlis.
3. Test Cartridge yuav tsum siv li ntawm 1 teev tom qab qhib lub pob.
Thaum lub glandular epithelium puas lawm, nws yuav inevitably ua puas lub G hlwb, ua rau ib tug tseem ceeb txo nyob rau hauv tus naj npawb ntawm G hlwb.
Nyob rau lub sijhawm no, kev txhim kho ntawm kev ua haujlwm zais cia ntawm G hlwb tsis tuaj yeem them nyiaj rau qhov txo qis hauv lawv cov lej, thiab tsis tuaj yeem txhawb kev tso tawm ntawm gastrin los ntawm G hlwb.
Kev tso tawm ntawm gastrin 17 yog nyob ntawm cov tshuaj hormones hauv plab hnyuv thiab cov yam ntxwv hauv plab hnyuv.
Raws li kev tso tawm ntawm gastric acid nce, somatostatin nce, thiab somatostatin inhibits kev tso tawm ntawm gastrin los ntawm kev ua haujlwm paracrine.
Gastrin 17 muaj cov kev tawm tswv yim tsis zoo nrog lub plab acid.Thaum lub plab corpus shrinks, gastric acid secretion yog txo, thiab inhibitory nyhuv ntawm G hlwb tsis muaj zog.
Cov kev tawm tswv yim tsis zoo ntawm cov txheej txheem tswj kev ua kom lub plab tso tawm ntawm gastrin los ntawm lub plab antrum G hlwb, uas txhawb kev zais ntawm gastric acid.
Thaum tshwm sim ntawm gastritis, nrog rau HP tus kab mob, theem ntawm gastrin 17 nce;Thaum hypergastrinemia tshwm sim, qib ntawm gastrin 17 kuj tseem tuaj yeem nce ntxiv.
Yog li ntawd, gastrin 17 tuaj yeem yog qhov kev ntsuas zoo ntawm kev noj qab haus huv ntawm lub plab mucosa.
Gastrin (gastrin, G) yog ib qho tshuaj hormones polypeptide, feem ntau zais los ntawm G hlwb hauv plab hnyuv mucosa.Hauv tib neeg lub cev, ntau dua 95% ntawm gastrin nrog rau kev ua haujlwm lom neeg yog α-amidated gastrin.
Yog li ntawd, amidated gastrin yog daim ntawv tseem ceeb ntawm gastrin, suav nrog kev sib xyaw ntawm G-17, G-34, G-14, G-71, G-52 thiab luv luv C-terminal sulfated hexapeptide amide, Cov ntsiab lus ntawm G-17. nce mus txog 80% mus rau 90%, uas yog daim ntawv tseem ceeb ntawm gastrin nyob rau hauv lub plab antrum.
Nws yog secreted los ntawm cov qog ntawm lub plab antrum thiab ncaj qha nkag mus rau hauv cov ntshav ncig.Nws yog ib qho cim tshwj xeeb ntawm kev ua haujlwm ntawm G cell.Gastrin 17 yog zais los ntawm G hlwb nyob rau hauv lub plab antral mucosa.
Gastrin Thaum lub mucosa dominated los ntawm gastric antrum hloov, cov ntsiab lus ntawm gastrin 17 cuam tshuam.Cov kev tshawb fawb tau pom tias thaum lub plab mucosa yog atrophied hnyav, qhov mob tau cuam tshuam rau nruab nrab 1/3 lossis qis dua 1/3 ntawm lub qog.
