Product Details
Background
Tau (S305) refers to a specific site on the tau protein, where a mutation in the S305N form is associated with a form of frontotemporal dementia. Research shows that phosphorylation at the S305 site normally inhibits tau aggregation, a process linked to neurodegenerative diseases like Alzheimer's and frontotemporal dementia. Mutations at this site, such as S305N, increase the proportion of a specific tau isoform (4R) and can disrupt normal brain cell function.
Application
To ensure optimal assay performance, AREX recommends conducting reagent titration tailored to each testing system for optimal detection results.
*Results are sample-specific. Please refer to your local assay conditions and test parameters for reference.

Data
Sandwich ELISA analysis of Tau (S305) by ARA6843 & ARA6840. Microtiter plates were coated with ARA6840 as the capture antibody. Recommbinant pTau217 protein (AXP6612) was applied as the antigen. Peroxidase conjugated pTau217 Antibody (ARA6843) served as the detection antibody. Result: ARA6843 and ARA6840 can be used as a matched antibody pair to detect and quantify the concentration of pTau217 .
Storage
Shipped at 4℃. Store at -20℃ for one year. Avoid repeated freeze/thaw cycles.
Note
For Research Use Only. Not for diagnostic, therapeutics, prophylactic or in vivo use.
FAQs
What are the main types of research antibodies and how do they differ?
Research antibodies are mainly divided into monoclonal antibodies and polyclonal antibodies. Monoclonal antibodies typically offer higher specificity and better batch-to-batch consistency, while polyclonal antibodies often provide stronger affinity but may show more variation between batches. The choice depends on your specific experimental needs.
How can I tell if a research antibody is suitable for my experiment?
It is recommended to carefully review the product datasheet for validated applications, species reactivity, recommended dilutions, and published references. For new antibodies, performing a small-scale validation with positive control samples is usually helpful.
Can improper storage of research antibodies affect experimental results?
Yes. Antibodies are sensitive to temperature, repeated freeze-thaw cycles, and contamination. Improper storage may lead to reduced activity, increased background, or weaker signals. It is best to follow the storage instructions provided in the product datasheet.
Why doesn’t the recommended dilution in the datasheet work well in my experiment?
The recommended dilution is based on the supplier’s test conditions. Factors such as sample type, fixation method, and detection system in your lab can influence the optimal working concentration. Performing a dilution series optimization in your own system is often necessary.
What precautions should I take when using a newly purchased research antibody for the first time?
It is advisable to briefly centrifuge the antibody (especially concentrated or lyophilized ones), then perform a small-scale pilot experiment using the recommended conditions. Recording the batch number and usage date is also helpful for future tracking.
