I have been studying on anti-angiogenesis. Within the scope, we need to VEGF165, anti-VEGF165 and SEMA3F biomaterials as earliest as possible. But too many types of VEGF, SEMA 3F and Anti-VEGF165A are available on the markets. it is too confusing. I wonder, what are the differences between them. Can you inform me about it, please? Lastly even if we order these proteins/antibody how many days will you delivery?

Thank you for contacting us. As you mention, we do have a number of related products available. The SEMA3F products we have in our catalog (such as ab39956) is a rabbit-polyclonal antibody against Semaphorin 3F. It is guaranteed to work with mouse and rat samples in Western blot (WB) and immunohistochemistry on PFA perfusion fixed frozen sections (IHC-FoFr). Semaphorins may play a role in cell motility; you may find more information about the target under the SwissProtID Q13275 (http://www.uniprot.org/uniprot/Q13275). The Semaphorin 3F peptide that is available under catalog number ab39955 is the immunogen that was used to generate the above antibody. This peptide can be used to block the signal detected by the antibody and thus helps to assess the specificity of the detection. https://www.abcam.com/index.html?datasheet=39955 https://www.abcam.com/index.html?datasheet=39955. https://www.abcam.com/index.html?datasheet=39956 https://www.abcam.com/index.html?datasheet=39956. We also have some VEGF165 proteins such as ab56620 and ab89574 in our catalog. These products are the actual Vascular endothelial growth factors (isoform A). You may find more detailed information on these growth factors for example under the SwissProtID P15692 (http://www.uniprot.org/uniprot/P15692). I would also encourage you to consult the latest literature available through PubMed and other resources in order to find the most up-to-date information about this specific research interest. The difference between the various catalog numbers may be that some of them are active proteins that can be used in functional studies, compared to others that have not been tested and cannot be guaranteed to work. https://www.abcam.com/index.html?datasheet=56620 https://www.abcam.com/index.html?datasheet=56620. https://www.abcam.com/index.html?datasheet=89574 https://www.abcam.com/index.html?datasheet=89574. Among our products we also have a number of antibodies against the various VEGF165 isoforms available, such as ab69479. These antibodies detect the protein of the species stated on the datasheet and are guaranteed to work in the mentioned applications. https://www.abcam.com/index.html?datasheet=69479 https://www.abcam.com/index.html?datasheet=69479. In general, all tested species and applications are specified on our datasheets, which are updated as soon as any new information is brought to our attention. If you decide to use one of our products in a species or application that has not been tested, please contact our Scientific Support team prior to the purchase as you might be eligible for our testing discount program. I am pleased to let you know that you are covered by our Abpromise should you decide to purchase one of our products: We will happily offer technical support and in the event that a product is not functioning in the applications cited on the product data sheet (and the problem has been reported within 6 months of purchase), we will be pleased to provide a credit note, free of charge replacement or refund. The delivery time depends on the product and if we have it in stock. As you can see at the top of each datasheet, the above mentioned products are currently available and if you order now you can get it tomorrow. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
