Shanghai Hengyuan is a well-established and trusted supplier of high-quality ELISA kits in China. We offer reliable products from reputable brands such as American R&D and TSZ, ensuring consistent performance and quality. ELISA technology is widely appreciated for its high specificity, sensitivity, stability, and ease of use. But which of these features stands out to you the most? It's important to note that not all ELISA kits deliver on these promises. Poorly chosen kits may fail to meet your expectations, especially when counterfeit products are involved. To help you make an informed decision, Shanghai Hengyuan shares the most comprehensive ELISA kit sensitivity detection program from 2015.
In general, if the target protein concentration in your sample is high, the sensitivity requirement may be less critical. However, when the concentration is low, sensitivity becomes a key factor. The lowest point on the standard curve of the kit is usually the most accurate. Below this level, the curve follows an "S" shape, making results less reliable and more of an estimate. Experimental errors can further affect accuracy, leading to unsatisfactory outcomes. Therefore, when selecting an ELISA kit, it’s better to focus on the lowest detectable concentration on the curve rather than just the sensitivity value listed on the product.
To accurately assess the sensitivity of an ELISA kit, it’s essential to use samples from disease prevention centers. Comparing the kit’s results with those from CDC-confirmed Japanese encephalitis virus IgM antibody positive samples helps evaluate its performance. The analysis considers the number of days since the onset of illness, as different stages may yield varying results. The test outcomes are categorized into low (P/? < 10), medium (10 ≤ P/? < 20), and high (P/? ≥ 20) based on the proportion of P/?. This approach ensures a more accurate evaluation of the kit's effectiveness.
Shanghai Hengyuan is dedicated to supporting life science research and adapting to the opportunities and challenges of the global economy. We provide ELISA kits for various species, including humans, rats, mice, and pigs, at competitive prices.
