Iron Homeostasis
Iron is a trace element required for several critical cellular processes. Too little iron (anemia) or too much iron (iron overload) can be harmful. While there is no known mechanism for the controlled excretion of excess iron, a handful of regulatory proteins control the absorption, transport, and storage of iron to maintain homeostasis.1,2 ALPCO offers several kits for the ...
On-boarding of new assays is critical for menu expansion and revenue growth, but the validation of a new assay requires a significant investment of time and resources. Proper planning can reduce errors and delays, minimizing validation time and reducing the impact on normal operations. Below are a few planning suggestions to help avoid common pitfalls and make the implementation of new assays a...
The use of the Enzyme-Linked Immunosorbent Assay (ELISA) technique has assisted both clinical and research laboratories in quantifying analytes of interest in heterogeneous samples. The sensitivity and specificity achievable with immunoassays are often ideal for biomarker testing. However, manually performing ELISAs is typically labor intensive and reliant on technique that can vary by user. La...
Chemiluminescence ELISA technology offers enhanced sensitivity with a very broad dynamic range. However, consistency in assay technique is especially important to ensure optimal performance from day-to-day and operator-to-operator. The following six tips may help to improve intra-assay and inter-assay precision when performing chemiluminescence immunoassays.
Tip 1: Use a Pipette to Transfer A...
Today, multiple immunoassay platforms exist, providing scientists and clinicians with the means to measure a variety of biomarkers1,2,3. However, research indicates some immunoassay platforms have limitations that can inhibit progress in the laboratory4,5,6. In an effort to provide researchers with a tool to overcome some of these limitations, ALPCO developed its STELLUX® chemiluminescence immu...
