This document introduces the features and characteristics of the product QuickStix Cry1Ab transgenic test paper from Shanghai Youlong Biotechnology Co., Ltd. It can be used to extract and detect Cry1Ab protein in transgenic corn, with a detection sensitivity of up to 1.0%.
The QuickStix AS 003 BG test kit is designed to extract and detect Cry1Ab protein in genetically modified corn (Bt11 or Mon810). It can detect as low as 1.0% Cry1Ab‑positive kernels (1 transgenic kernel in 100).\n\nThe procedure includes weighing and grinding the appropriate number of kernels, extracting the protein with water, loading the extract onto the test strip, incubating for 5 minutes, and reading the control and test lines. The kit should be kept sealed at room temperature, with refrigeration extending shelf life. This manual is written in Chinese.
| Detection sensitivity | 1.0% (1 transgenic kernel in 100) |
|---|---|
| Sample weight and grinding time | 10‑25 g, 30 s (or 25‑65 g, 30 s) |
It can detect Cry1Ab protein at a level of 1.0%, meaning 1 transgenic kernel in a batch of 100 kernels.
Read the result after 5 minutes of incubation; positive lines may appear even sooner.
Keep the strips sealed at room temperature; refrigeration prolongs shelf life.
