Serum Ferri Ion Content Assay Kit
Notiz: Nehmen Sie vor dem Test zwei oder drei verschiedene Proben zur Vorhersage.
Betriebsausrüstung: Spectrophotometer
Katzennummer: BC1730
Größe: 50T/48S
Komponenten:
Reagenz I: Pulver×2, storage at 4℃. Hinzufügen 10 mL distilled water before use.
Reagent Ⅱ: Pulver×2, storage at 4℃. Hinzufügen 313 μL glacial acetic acid and 10 mL distilled water before use. Standard Solution: Liquid 3 ml×1, 1000 μmol/L Fe3+ standard solution, storage at 4℃. Add distilled water dilute 8 times to form a standard solution of 125 μmol/L before use.
Produktbeschreibung:
Serum iron is the iron bound with transferrin in blood, which is often used to distinguish non-iron deficiency anemia and iron-deficiency anemia.
Fe3+ is reduced by sodium sulfite to Fe2+, which reacts with 2,2-dipyridine-bipyridine, have an absorption peak at 520 nm. According measure absorbance at 520 nm can reflect serum iron concentration.
Erforderliche, aber nicht bereitgestellte Reagenzien und Ausrüstung.
Spectrophotometer, Zentrifuge, glacial acetic acid, adjusted transferpettor, 1 mL glass cuvette, chloroform and distilled water.
Verfahren:
- Preheat the spectrophotometer for 30 Mindest, Wellenlänge anpassen 520 nm, set zero with distilled
- Dilute standard solution to 125 μmol/L with distilled
- Add reagents with the following list:
| Reagent Name (μL) | Blank tube (AB) | Test tube (BEI) | Standard tube (ALS) |
| Distilled water | 400 | ||
| Standardlösung (125 μmol/L) | 400 | ||
| Serum(Plasma) | 400 | ||
| Reagenz I | 400 | 400 | 400 |
| Reagenz II | 400 | 400 | 400 |
| Mix thoroughly, incubate in boiling water bath for 5 Mindest, cooling liquid. Hinzufügen 200 μL chloroform (required but not provided). Mix thoroughly, room temperature, 10000 rpm centrifuge for 10 Mindest. Nehmen 700 μL supernatant to 1 mL glass cuvette. Measure absorbance at 520 nm. Recorded as AB, BEI, ALS. | |||
Berechnungen
Serum iron (μmol/L)=[Cs×(AT-AB)÷(As-AB)]= 125×(AT-AB)÷(As-AB)
Cs: Fe3+ standard solution, 125 μmol/L.
Notiz:
- There is less iron in the serum, so the vessels (EP tubes) should be noted to avoid iron contamination.
- Reagent I and Reagent II are unstable. It needs to be prepared when the solution will be used, and the newly prepared reagent can only be used on the same day.
- When At- Ac＞5, please dilute the Serum to appropriate concentration with distilled water.
