Human CTLA4(Cytotoxic T-lymphocyte protein 4) ELISA Kit

References #2
Category:

This kit is based on Double antibody-Sandwich ELISA detection method and takes 4h assay time. The microplate provided in this kit has been precoated with anti CTLA4 antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with CTLA4 bound to precoated antibody. Wash unbound components and add HRP-Streptavidin Conjugate (SABC). Wash unbound components again and add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Calculate the concentration of CTLA4 in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Ordering & Delivery
How do I place an order?
Use the Inquiry button on this page or write to tekintolga89@gmail.com. Include the catalogue number and the quantity you need.
What is the dispatch time?
In-stock items are dispatched within 1-3 business days. Items that need to be produced take longer; we confirm the date when you order.
Do you ship outside Türkiye?
Shipping is arranged case by case. Contact us with the destination and we will quote carriage and lead time.
Storage & Handling
How should an unopened kit be stored?
At 2-8 °C unless the datasheet says otherwise. Do not freeze a kit that is not marked for freezing.
How long is an opened kit stable?
It depends on the component. The Kit Components table on this page lists the storage condition for each item after opening.
What should I do if the shipment arrives warm?
Photograph the package and contact us the same day. Do not use the kit until we have confirmed it is still within specification.
Assay Questions
Which sample types can I use?
The Sample Type row in the specifications above lists the validated matrices for this product. Other matrices need validation on your side.
My background is too high. What should I check?
The usual causes are insufficient washing, contaminated buffers, or too much detection antibody. Our Protocol pages cover the full troubleshooting sequence.
Can I run fewer wells than the kit provides?
Yes. Dismountable microplates let you use part of a plate and reseal the rest with the desiccant supplied.
Technical Support
Something did not work. What do you need from me?
Send the catalogue number, the lot, your protocol deviations and the raw OD values. That is usually enough to identify the cause.
Do you provide a certificate of analysis?
Yes, per lot. Ask for it with the catalogue number and lot number.
