제목 효소 안정화제 ST2010, ST3010, ST4010
Stabilizer의 ST 시리즈는 POD, ALP 등의 표식항체를 그대로 희석하여 사용하는 것 만으로 표식 항체 보존성이 향상됩니다.
 

Stabilization reagents ST2010

- Features -

-Peroxidase stabilizer for enzyme immunoassay
-No bio-derived materials
-Excellent stability for POD conjugate protein

-Usage-

-Use it like a usual stabilizer
-Use from 1- to 25-fold dilution --- we recommend stock solution ---
-We recommend to dilute the POD conjugate over tenfold

The POD was diluted to optimum concentration (0.1 mg/mL in this example) with the direct POD stabilizer solution. The POD solution was filtrated using a filter with a pore size of 0.22 m, and stored at 40°C. The POD activity was measured with an H2O2-ABTS coloring-system. The activity at the initial time (0 days) was indicated as 100%.
 
 

Stabilization reagents ST3010, ST4010

- Features -

-ALP stabilizer for enzyme immunoassay
-No bio-derived materials
-Excellent stability for ALP conjugate protein

-Usage-

-Use it like a usual stabilizer
-Use from 1- to 25-fold dilution --- we recommend stock solution ---
-We recommend to dilute the ALP conjugate over tenfold

-Precautions for use-

The product contain 0.09% sodium azide as a preservative. Be careful not to ingest it by mistake and take care when disposing of it.

Results show ALP activity remained at least 80% after 4 weeks 37℃

Method

The ALP conjugate was dlluted 100 times
by ST3010 or ST4010.
The solutions were stored at 37°C for 4 weeks.
The ALP activities were estimated by ALP assay kit.
0 days activity was indicated as 100%
