兔抗叙利亚仓鼠IgG H&L (Biotin) (ab6782)

I apologise for the delay in responding to you, I have at last received feedback from the laboratory that tested ab33483 and include their response below: I have had a look through your customers protocol and note that it differs somewhat from our recommended protocol for cryostat sections. So firstly from their protocols: 1. I note sections appear to be stored in a freezer prior to staining. Some antigens are more sensitive to this than others, this may be the case here. I would recommend using freshly sectioned material 2. Following acetone fixation they have included a triton step (for the DAPI?). This may not be compatible with staining for CD11c using this antibody. I would suggest omitting this step. I note from the literature that such a step is not included in publications reporting successful staining with this antibody. 3. We do not support the use of Immunofluorescence for this antibody. I do not know whether there is sufficient sensitivity to allow the use of TRIT-C for its detection. I would suggest the use of a peroxidase-DAB protocol as has been used in all the publication reporting successful. My gut feeling is that it may be the Triton X-100 that may affect the epitope recognised by the antibody. Just omitting this step may help restore antigenicity. Please find a list of publications where this has been used successfully for IHC on cryostat sections. There may be further appropriate advice in these. 1: Witmer-Pack MD, Crowley MT, Inaba K, Steinman RM.

Reference 1 has some great pictures of staining in the liver and in spleen with N418 and other antibodies such as F4/80 and FA-11 etc. I hope this advice will be useful. Please do not hesitate to contact me if you still experience problems with those recommendations, if you purchased the antibody in the last 90 days I would be happy to offer you a refund,

Thank you for your enquiry. The protocol quoted in the link you kindly provided does not seem to mention our antibodies but antibodies from other companies. In our experience the secondary ab6782 does not give background problems and does not need to be pre-absorbed. If you experience any problems or need further advice regarding your IHC protocol please do not hesitate to contact me, I would be happy to look at your full protocol,

This antibody is not recommended for Armenian hamster IgG.
