Deskripsi Produk:

Trigliserida(PT) is a fat molecule formed by long-chain fatty acids and glycerol, which is not only the main component of cell membrane, but also an important respiratory substrate. The TG is extracted with isopropyl alcohol, then hydrolysis to glycerol and fatty acids after saponification of TG by KOH. Glycerol is oxidized by periodic acid to form formaldehyde. Condensation of formaldehyde and acetylacetone to form yellow components in presence of chloride ions. The yellow component has a characteristic absorption at 420 nm and proportional to the TG content.

Reagen dan Peralatan Diperlukan tetapi Tidak Disediakan:

Spektrofotometer/pembaca lempeng mikro, kuvet kaca mikro/pelat dasar datar sumur 96, n-heptane, isopropyl alcohol, mandi air, pipet yang dapat disesuaikan, distilled water and 125 mL of empty bottle.

Prosedur:

SAYA. Persiapan sampel:

• Jaringan:

Ice-bath homogeneity is conducted according to the ratio of tissue mass (G): Reagent Ⅰ volume (ml) = 1: 5~10 (it is suggested to take about 0.1 g of tissue and add 1 mL Reagen I). Sentrifugasi di 8000 g untuk 10 minutes at 4℃, supernatant is used for test.

• Bacteria:

Mengumpulkan 5 million cells or bacteria into the centrifuge tube, then discard the supernatant, final add 1 mL Reagen I. Splitting bacteria or cell with ultrasonic for 1 menit (kekuatan 20%, work time 2s, interval 1s). Sentrifugasi di 8000 g untuk 10 minutes at 4℃, supernatant is used for test.

• Serum: Deteksi

II. Prosedur:

1. Preheat Spectrophotometer for 30 menit, adjust the wavelength to 420 nm, atur nol dengan air suling.
2. Preheat water bath to 65℃.

3. Detect TG content:

Setelah dingin, transfer liquid from the EP tube to a micro glass cuvette/96 well flat-bottom plate, and determine the absorbance at 420 nm.

Catatan: Blank tube and standard tube only need to be measured once.

AKU AKU AKU. Perhitungan:

1) Serum:

PT(mg/dL)= C×(PADA- AB)−(SEBAGAI- AB)×100 =(PADA- AB)−(SEBAGAI- AB)×100

2) Jaringan:

Konsentrasi protein:

PT(mg/mg prot)= C×V×(PADA- AB)−(SEBAGAI- AB) −(Cpr×V)=(PADA- AB)−(SEBAGAI- AB) −Cpr

Berat sampel:

PT(mg/g) = C×V×(PADA- AB)−(SEBAGAI- AB) ÷W=(PADA- AB)−(SEBAGAI- AB) −W

3 ) Bacteria or cells:

PT(U/104 cell) = C×(PADA- AB)−(SEBAGAI- AB) ÷D=(PADA- AB)−(SEBAGAI- AB) ÷D 1dL =100 mL;

V: The volume of reagent1, 1 ml;

C: Standard concentration, 1 mg/ mL;

Cpr: Konsentrasi protein sampel (mg/mL); W: Berat sampel(G);

D: Density of bacteria or cell, 104 cell/mL.

Catatan:

1. There are volatile substances in the kit. Gloves and masks should be worn during the experiment. The reagent bottle cap should be closed in time after
2. After the addition of Reagent Ⅱ, it is necessary to repeatedly and violently vibrate, so that the triglyceride in the test solution can be fully extracted, and the oscillation amplitude, time, repeated times and waiting for stratification time should be
3. In order to ensure the repeatability of the test, the cooling time after each water bath should be
4. If the OD value of the test tube is greater than 1.5, it is recommended to dilute the sample with Reagent I properly before testing, and multiply it by the corresponding dilution multiple during calculation.
