Creative Biolabs has launched matched antibody pairs that are specifically designed and screened for antigen detection kit development, which are suitable for different diagnostic assays, such as chemiluminescent immunoassay (CLIA), ELISA, gold immunochromatography assay, etc. The sensitivity of matched antibody pair suitable for sandwich ELISA application is verified by using recombinant antigens. For some specific products, the pair sets have been verified using inactivated virus, serum, urine samples. Creative Biolabs will provide you high-quality antibody pairs to support your assays/kits development. Our Product lines are continuously updated.
Here, our frequently asked questions (FAQs) including Purchasing FAQs and Technical FAQs will answer your commonly asked questions on products purchasing. You can obtain most answers to your questions in the FAQs during your ordering process. If you still have any questions or in antibody research, please do not hesitate to contact us.
We mainly accept online orders, please see the contact us page for address, telephone, fax, and email details. Once we receive your Purchase Order (PO), we will proceed with it as soon as possible.
To process your order, we need the following information:
After an approved purchase order is transmitted to us, if the product(s) has not been shipped, the requisitioner must inform us that the product(s) is not required, that we will not ship the product(s), and that a formal purchase order change order (POCO) will be issued and transmitted to us.
All in-stock orders received Monday through Fridays will be shipped in 1-2 weeks
For Europe and North America, we ship for delivery in 2-3 days. For other parts of the world, depending on the country, the transit time is between 3-5 days.
Generally, most of the products displaying on our website are in stock. If you want to know the exact product inventory information, please contact us.

Matched antibody pairs are now having a revamp in some research areas, not only the “classical” ELISA use, but also IP-WB and even protein-protein interaction studies.
Our antibody pairs come in 2 formats:
Individual capture and detector antibodies can also be purchased separately. For desired size, please contact us.
This will depend on how closely related the target species to your species of interest is. You can obtain the different protein sequences from UniProt and check the sequence mapping using the analysis tool. Alternatively, quickly check whether the epitope of your antibody matches a sequence of the untested species.
Creative Biolabs is unable to guarantee that an antibody will work in an untested species, even if the sequence alignment is high. There are many variables involved in the determining whether an antibody will bind in another species. If there are no alternatives available, and it is necessary for you to consider purchasing an antibody for use in a species that is not tested, we recommend checking the sequence alignment of the immunogen with the protein you are interested in.
For some of our antibodies cross reactivity data is available. Please check the ‘specificity’ section on the datasheet. If information is not available here, we recommend checking the sequence alignment of the immunogen with the isoforms or other proteins you are interested in.
For some of our antibodies, the immunogen sequence is readily available on the product datasheet. However, some immunogen sequences, are proprietary. We invest a lot of time and effort into selecting immunogen sequences in order to deliver the most effective antibodies. We sometimes decide to protect this information and we are unable to release this information, even on request.
The concentration used will depend on the batch, application the antibody is being used for and the expected concentration of the target protein. Please remember that the following dilutions and concentration estimates are simply recommended as a starting point, and it may be necessary to adjust the dilution based on the experimental results.
|Culture supernatant||Ascites||Whole antiserum||Purified antibody|
|IHC/ICC||neat - 1/10||1/100||1/50-1/100||5 ug/ml|
|Concentration estimate||1-3 mg/ml||5-10 mg/ml||1-10 mg/ml|
The datasheets contain the most up-to-date information we have available to us about this product. Where we find additional information, the data sheets are updated live on the website immediately, so they should never be out of date.
We do not always have information available on the most suitable antigen retrieval method for an antibody in immunohistochemistry. This will often require a certain amount of optimization by the end user.
We recommend always storing the antibody as directed on the datasheet. We are unable to guarantee how the antibody will perform if not stored as stated on the datasheet. Most of our antibody pair products are shipped in a 4ºC refrigerated packaging, which has been shown to provide a stable environment for products in transit. If you have any specific shipping requirements, please contact us.
The size of the aliquots will depend on how much one typically uses in an experiment. Aliquots should be no smaller than 10 µl; the smaller the aliquot, the more the stock concentration is affected by evaporation and adsorption of the antibody onto the surface of the storage vial.
We sometimes have to discontinue a product. This can be for several reasons, such as poor sales, or production difficulties. On some occasions, this can be for quality issues, but this is not always the case. If we have a replacement for the antibody, we will supply the catalog number when you attempt to bring up the discontinued product’s datasheet.
