  • ab73891 staining SRSF3 in mouse E9.5 embryo tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with formaldehyde, permeabilized with 0.5% Triton X-100 and blocked with 1% BSA + 10% goat serum + 0.1% Triton X-100 in PBS for 1 hour at 20°C. Samples were incubated with primary antibody (1/100 in PBS + 1% BSA + 10% goat serum + 0.1% Triton) for 16 hours at 4°C. An Alexa Fluor® 594-conjugated goat anti-rabbit IgG polyclonal (1/200) was used as the secondary antibody.

Answer

Thank you for your enquiry.

I can confirm you are correct, these are the same antibody. We have sourced the same antibody from two different places and given them different product codes. The sources have tested them in different applications, which is why we have chosen to keep both on the catalog, to provide a wider selection of suitably tested antibodies for customers.

I hope this helps to clarify any confusion. If you have any further questions, please do not hesitate to contact us.
