The immunochromatographic uncut sheet is a key materials for rapid test kit and FIA test kit, which can help you establish point-of-care testing business as soon as possible.
In the field of in vitro diagnosis (IVD), accuracy, speed, ease of operation and controllable cost are the core demands of both clinical and production ends. As a key semi-finished product for rapid test kit and FIA test kit, the immunochromatographic uncut sheet plays an irreplaceable role in improving efficiency and reducing costs. This article focuses on its definition and core advantages to help you quickly grasp its value.
What is an Immunochromatographic Uncut Sheet?
An immunochromatographic uncut sheet product is a large-size detection substrate developed based on immunochromatographic technology (mainly colloidal gold method, expandable to fluorescence method). Simply put, it is the core semi-finished product of test cards, which precisely assembles key components such as nitrocellulose membrane (NC membrane), gold-labeled conjugate pad, sample pad and absorbent paper on a PVC base plate to form a large "uncut sheet".
Different from finished test kits, the uncut sheet focuses on mass production and customized adaptation. It can be cut into strips of different specifications according to needs, and flexibly adjust formulas, sizes and detection indicators to adapt to various sample types (such as serum, plasma, stool, nasal swabs, etc.). It is a key link connecting core raw materials and terminal finished products, widely used in IVD reagent production and rapid detection scenarios.
Core Product Advantages
Our immunochromatographic uncut sheet, which including rapid test uncut sheet and FIA uncut sheet, follows standardized processes in R&D, component selection and production, focusing on practicality, stability and cost-effectiveness, with four core advantages to meet diverse customer needs:
1. High Accuracy and Low Error
We select high-activity antigens and antibodies as core raw materials, combined with optimized buffer systems, to greatly improve the binding efficiency of antigens and antibodies. It also strictly controls cross-reactions, effectively avoiding the impact of interfering substances, reducing false positive and false negative cases, and providing reliable qualitative judgment for various detection scenarios.
2. Customizable and Strongly Adaptable
It breaks the limitation of fixed specifications and can be fully customized on demand. In terms of size, it supports standard 60mm*300mm and various non-standard sizes; in terms of indicators, it covers infectious diseases, digestive tract detection, hormone detection, respiratory pathogens and other qualitative detection items; in terms of samples, it is compatible with serum, plasma, whole blood, stool, nasal swabs and other sample types, realizing precise adaptation to different needs.
3. Excellent Stability and Convenient Storage
High-quality PVC base plate, high-stability NC membrane and gold-labeled conjugate pad are adopted, with tight component bonding, not easy to delaminate or deform. After multiple stability tests, the product can be stored for 36 months in a cool and dry environment at 2~30℃, with sealed in foil bag. The uncut sheet shape is convenient for batch packaging and transportation, with extremely low loss rate, greatly reducing storage and logistics costs.
4. High Cost-Effectiveness
For the mass production needs of IVD enterprises, large-scale production technology is adopted to significantly reduce unit production costs. The uncut sheet can be directly cut for use without additional assembly of core components, reducing production processes and improving efficiency. We also provide one-stop service of "uncut sheets + technical support", helping customers simplify the supply chain and reduce R&D and production thresholds, especially suitable for small and medium-sized IVD enterprises .
As a must-have semi-finished product in rapid IVD detection, the immunochromatographic uncut sheet perfectly meets the core demands of accuracy, efficiency and cost control.
