Theory

Alkaline phosphatase (AKP/ALP) is a zinc-containing glycosylase that hydrolyzes various natural and synthetic phospholipid monoester compounds in alkaline conditions. AKP/ALP is widely distributed in various organs of the human body, mainly in the liver. In alkaline environment, AKP/ALP catalyzes phenyldisodium phosphate to produce free phenol. The phenol reacted with 4-amino-antipyrine and potassium ferricyanide to form red derivatives with characteristic light absorption at 510 nm. AKP/ALP activity was calculated by measuring the absorbance increase rate at 510 nm.

General Notes

This product is only for scientific research use, not for clinical diagnosis. See the Safety Data Sheet for hazard and safe handling information.

2, do not mix components between different batch numbers and different manufacturers; Otherwise, it may lead to abnormal results.

3, when mixing or redissolving the components, avoid air bubbles.

4, frequently change the suction head to avoid cross contamination between the components.

5, before the start of the experiment, ensure that all the components and equipment in the appropriate temperature.

6, Chromogen and Chromogen B and Chromogen C all needs to avoid light preservation. Chromogen C cannot be used again after it turns bluish-green.

After adding Chromogen C, it must be mixed immediately, otherwise the color will not be complete.

Storage Temp.

2-8℃, stored in the dark, valid for 12 months.

Sample preparation

Note

Fresh samples are recommended, and if experiments are not performed immediately, samples can be stored at -80 ° C 1 month.

Tissue samples: Weigh about 0.1 g sample, add 1 mL Extraction Buffer, homogenize in an ice bath, centrifuge at 10,000 rpm for 10 min at 4 ° C, take the supernatant and place it on ice for testing.
Serum (plasma) : plasma and serum can be directly used for determination. EDTA and citrate can not be used in plasma preparation, but other anticoagulants can be used.
urine: direct measurement.

Note

To measure protein concentration, use Item No. : abs9232 ? protein quantification kit (BCA method) was used to determine the protein concentration of samples.

Experimental procedures

The microplate reader or visible light spectrophotometer was preheated for more than 30 min, and the wavelength was adjusted to 510 nm.

The results were calculated as follows:

Note

We provide you with the calculation formula, including the derivation process calculation formula and the concise calculation formula. The two are exactly the same. The concise formula in bold is recommended as the final formula.

1, according to the protein concentration calculation

Active unit definition

37 ℃ per minute per mg protein catalytic produce 1 mu mol of phenol as a unit of enzyme activity. AKP/ALP (U/mg prot) = [C standard x (A determination - A contrast) present sample (A standard - A blank) * V] present sample (Cpr) V) present T = 0.133 x (A determination - A contrast) present (A standard - A blank) present Cpr

2, fresh weight calculation according to the sample

Active unit definition

37 ℃ in the organization to make 1 mu per minute per gram mol of phenol as a unit of enzyme activity.

AKP/ALP (U/g fresh weight) = [C standard x (A determination - A contrast) present sample (A standard - A blank) * V] present (W present V sample extraction (V) present T = 0.133 x (A determination - A contrast) present (A standard - A blank) present W

3, according to the liquid volume calculation

One unit of activity was defined as the catalytic production of 1 μmol phenol per minute per milliliter of blood or urine at 37 ° C.

AKP/ALP (U/mL) = [C standard x (A determination - A contrast) present sample (A standard - A blank) * V] present V sample present T = 0.133 x (A determination - A contrast) present (A standard - A blank)

C standard

concentration of standard, 2 μmol/mL; V: join the upper clear liquid deposition reaction system, 0.004 mL; T: reaction time, 15 min; V extraction: Add extraction liquid volume, 1 mL; W: fresh weight of sample, g; Cpr: the protein concentration in the supernatant fluid, mg/mL.
