Konfigurierbare Panels & Premixed-Kits
Unser breites Angebot enthält Multiplex-Panels, für die Sie die Analyten auswählen können, die am besten für Ihre Anwendung geeignet sind. Unter einem separaten Register können Sie das Premixed-Cytokin-Format oder ein Singleplex-Kit wählen.
Kits für die zelluläre Signaltransduktion & MAPmates™
Wählen Sie gebrauchsfertige Kits zur Erforschung gesamter Signalwege oder Prozesse. Oder konfigurieren Sie Ihre eigenen Kits mit Singleplex MAPmates™.
Die folgenden MAPmates™ sollten nicht zusammen analysiert werden: -MAPmates™, die einen unterschiedlichen Assaypuffer erfordern. -Phosphospezifische und MAPmate™ Gesamtkombinationen wie Gesamt-GSK3β und Gesamt-GSK3β (Ser 9). -PanTyr und locusspezifische MAPmates™, z.B. Phospho-EGF-Rezeptor und Phospho-STAT1 (Tyr701). -Mehr als 1 Phospho-MAPmate™ für ein einziges Target (Akt, STAT3). -GAPDH und β-Tubulin können nicht mit Kits oder MAPmates™, die panTyr enthalten, analysiert werden.

The Single Molecule Counting (SMC™) Human SARS-CoV-2 S1 IgA kit uses a fluorescent sandwich immunoassay technique to measure SARS-CoV-2 S1 IgA in Human EDTA Plasma and Serum samples. A Human SARS-CoV-2 S1 capture protein has been pre-coated onto paramagnetic microparticles (beads). The user pipettes beads and samples into uncoated microplate wells. During incubation, the SARS-CoV-2 S1 IgA present in the sample binds to the capture protein on the coated beads. Unbound molecules are washed away during the subsequent wash steps. Fluor-labeled detection antibody is added to each well and incubated. This detection antibody recognizes and binds to IgA antibodies against SARS-CoV-2 S1 that have been captured onto the beads, thus completing the immunosandwich. Elution buffer is then added and incubated. The elution buffer dissociates the bound protein sandwich from the beads surface releasing the labeled antibodies. These antibodies are separated during transfer to a final microplate. The plate is loaded into the SMCxPRO™ System where the labeled molecules are detected and counted. The number of fluor-labeled detection antibodies counted is directly proportional to the amount of SARS-CoV-2 S1 IgA present in the sample when captured. The amount of SARS-CoV-2 S1 IgA in unknown samples is qualitatively assessed in raw signal to determine COVID-19 infection when compared against known negative samples.
Background Information
Immunoassay-based serology techniques play key roles in many SARS-CoV-2 research programs due to their ability to identify and characterize sample of infected individuals long after initial exposure. However, many traditional assay platforms, due to limitations in sensitivity and resolution, may not be truly optimal for use in situations where low-level characterization and stratification of SARS-CoV-2 antibody responses are essential, such as population studies, temporal infection timecourse experiments, and evaluating vaccine efficacy. The Single Molecule Counting (SMC™) ultrasensitive immunoassay platform has been harnessed toward the development of new products for detecting SARS-CoV-2 mediated antibody response. The new SMC™ SARS-CoV-2 S1 IgA kit can be used by researchers to accurately understand the extent of SARS-CoV-2 infection in society, thoroughly profile immune response after natural or vaccine-induced exposure, demonstrate persistence of long-term antibody post-infection, and understand the extent of immune heterogeneity among individuals and subpopulations.

Precision, %
The assay variation of the SMC™ Human SARS-CoV-2 S1 IgA Immunoassay kit were studied using fourteen plasma samples, run in triplicate in three separate runs.
Mean intra-assay variation for all samples was < 9%.
Mean inter-assay variation for all samples was < 15%.
