GAD65 Antibody ELISA With Extended Reportable Range: Validation and Guidance for Neurological Practice

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To (1) validate GAD65‐ELISA detection and quantification for type 1 diabetes mellitus and autoimmune neurological diagnoses, (2) correlate ELISA results (reference range < 5 IU/mL) with established radioimmunoprecipitation assay (RIA; ≤ 0.02 nmol/L), and (3) define ELISA clinical utility and pitfalls.

LIMIT OF DETECTION (LOD) AND LIMIT OF QUANTITATION (LOQ) OF DR 1900 SPECTROPHOTOMETER FOR DYES ANALYSIS

Berkala Penelitian Teknologi Kulit, Sepatu, dan Produk Kulit
Dyes is not easily degraded in the environment. It can be causing environmental pollution. The concentration of these dyes must be monitored when using it in a process. The most common method to measuring dye’s concentration is spectrometry, such as using dr 1900 spectrophotometer.

Peripheral Neutrophil Activation and Extracellular Trap Formation in Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
Markers of neutrophil activation are increased in plasma during ALS, and markers of NET formation associate with ALS survival. ABSTRACT Objectives Peripheral neutrophil levels in amyotrophic lateral sclerosis (ALS) inversely correlate with survival, suggesting a role for neutrophils in disease progression.
