Simultaneous Distinction of Monospecific and Mixed DFS70 Patterns During ANA Screening with a Novel HEp-2 ELITE/DFS70 Knockout Substrate10:05

Simultaneous Distinction of Monospecific and Mixed DFS70 Patterns During ANA Screening with a Novel HEp-2 ELITE/DFS70 Knockout Substrate

DFS70 autoantibodies mimic common disease-associated antinuclear antibody patterns making accurate interpretation challenging when using conventional HEp-2 substrates. The protocol describes advantages of novel engineered HEp-2 substrate over conventional HEp-2 in ANA screening and distinguishing DFS70 patterns with high confidence in both monospecific and mixed ANA positive...

Detection of Anti-MDA5 Autoantibodies Using HeLa Cells and Immunocytochemistry with Light Microscopy10:55

Detection of Anti-MDA5 Autoantibodies Using HeLa Cells and Immunocytochemistry with Light Microscopy

We provide a step-by-step immunocytochemistry (ICC) methodology for detecting anti-MDA5. This approach involves cell fixation, permeabilization, antibody incubation, and imaging techniques, which allow for the accurate detection of anti-MDA5 autoantibodies, aiding in the diagnosis of rapidly progressing interstitial lung disease in myositis patients.

Electrochemiluminescence Assays for Human Islet Autoantibodies

Here, we presented the methods to detect human islet autoantibodies using electrochemiluminescence (ECL) assays. The protocol, used to predict type 1 diabetes, can be expanded upon to detect autoantibodies for other autoimmune...

An Assay to Detect Autoantibodies in Human Serum using a Hippocampal Neuronal Culture

This video demonstrates a technique for identifying antibodies against specific antigens in a sample using a rat hippocampal neuronal culture. By exposing cultured neurons to patient samples containing autoantibodies targeting N-Methyl-D-aspartate receptors (NMDARs), the presence of autoantibodies bound to the neuronal surface is revealed through...

Granulocyte-dependent Autoantibody-induced Skin Blistering

In the animal model described in our present work, purified IgG antibodies against a stretch of 200 amino acids (aa 757-967) of collagen VII are injected repeatedly into mice reproducing the blistering phenotype as well as the histo- and immunopathological features characteristic to human epidermolysis bullosa acquisita...

A Simple Cell-based Immunofluorescence Assay to Detect Autoantibody Against the N-Methyl-D-Aspartate (NMDA) Receptor in Blood07:20

A Simple Cell-based Immunofluorescence Assay to Detect Autoantibody Against the N-Methyl-D-Aspartate (NMDA) Receptor in Blood

We ectopically expressed NR1 subunit of NMDA receptor tagged with green fluorescent protein in human embryonic cells (HEK293) as antigen to detect autoantibodies against NMDA receptor in the blood of patients suspected with autoimmune encephalitis. This simple method may be suitable for screening purposes in clinical...
