TfR (Transferrin R) Antibody (OX26) - BSA Free

Western Blot: TfR (Transferrin R) Antibody (OX26) [NB200-585] - Total protein from rat adrenal gland cells (PC12) and rat placenta was separated on a 7.5% gel by SDS-PAGE, transferred to PVDF membrane and blocked in 5% non-fat milk in TBST. The membrane was probed with 2 ug/ml anti-CD71 in 1% milk, and detected with an anti-mouse HRP secondary antibody using chemiluminescence.

Immunocytochemistry/Immunofluorescence: TfR (Transferrin R) Antibody (OX26) [NB200-585] - PC-12 cells were fixed for 10 minutes using 10% formalin and then permeabilized for 5 minutes using 1X TBS + 0.5% Triton X-100. The cells were incubated with anti TfR/Transferrin R (OX26) NB200-585 at a 1:100 dilution overnight at 4C and detected with an anti-mouse DyLight 488 (green) at a 1:500 dilution. Actin was detected with Phalloidin 568 (red) at a 1:200 dilution. Nuclei were counterstained with DAPI (blue). Cells were imaged using a 40X objective.

Immunohistochemistry-Paraffin: TfR (Transferrin R) Antibody (OX26) [NB200-585] - Analysis of FFPE mouse spleen using TfR (OX26) antibody at 1:50 on a Bond Rx autostainer (Leica Biosystems). The assay involved 20 minutes of heat induced antigen retrieval (HIER) using 10mM sodium citrate buffer (pH 6.0) and endogenous peroxidase quenching with peroxide block. The sections were incubated with primary antibody for 30 minutes and Bond Polymer Refine Detection (Leica Biosystems) with DAB was used for signal development followed by counterstaining with hematoxylin. Whole slide scanning and capturing of representative images was performed using Aperio AT2 (Leica Biosystems). Plasma membrane staining was observed. Staining was performed by Histowiz.

FAQs for TfR (Transferrin R) Antibody (NB200-585). (Showing 1 - 2 of 2 FAQs).

1. A customer would like to use this antibody to perform an functional assay. The customer would like to know whether this antibody will block the binding of transferrin to the receptor. On the other hand, would you mind to provide the immunogenic sequence of this antibody?
   • Unfortunately, this clone has not been mapped and the sequence of the epitope recognised is currently unknown. All that is currently known is that the clone binds an extracellular region not involved in transferrin binding.
2. I was wondering if you have amino acid sequence information available for this monoclonal mouse anti-Rat TfR (Ox26) antibody.
   • The immunogen used to create this product is PHA activated rat lymphocytes (SwissProt: Q99376). We have not mapped the epitope for the product.
