Application of Automated Storage and Retrieval Systems

Automated storage and retrieval systems (ASRS) are designed to automate the storage and retrieval of parts and items. These types of systems first appeared in the 1960s, and started by handling large, palletized loads. However, as they became more popular, they began to handle smaller, more individual loads. Today, AS/RS operate on a computer-controlled system […]

What Factors May Affect Elisa Results?

The amount of antibody coated on the plate shall be proportional to the sensitivity of the assay. For most immunoassays, the 4 or 5 parameter logistic model is far better than the linear, quadratic or log-log linear fashions. These fashions are available in several software program packages, and are easy to implement even in an […]
