Data show that patients who have factor VIII (FVIII) inhibitor titers of 20 or higher BU/mL took longer to achieve complete responses (CR) and had lower CR rates vs patients with lower titers.

In a recent study posted to the medRxiv* preprint server, researchers assessed the changes in the immunoglobulin (Ig) titers against the receptor-binding domain (RBD) of the spike (S) protein of the ...

In a recent study posted to the medRxiv* preprint server, researchers evaluated the impact of virus-neutralizing antibody (vnAb) titers against severe acute respiratory syndrome coronavirus 2 ...

In this Learning Lab we will discuss some common methods used to measure viral titers and considerations one should bear in mind when interpreting the results from different assays used to quantify ...

The true etiology of the peak in C.M.'s anti-D antibody titer to 1:32, with subsequent conversion to a negative antibody status before delivery, cannot be explained with certainty. On the basis of her ...

Panel A shows spike protein sequences for the omicron BA.2, BA.2.75.2, XBB.1, BA.5, BF.7, and BQ.1.1 subvariants; mutations as compared with the WA1/2020 spike protein are shown. Mutations as compared ...

New Instrument Counts and Sizes Viruses and Their Aggregates in Liquid Suspension There are two main categories of viral vaccines—live (attenuated) and killed (inactivated) vaccines. A live attenuated ...
