    Human paraffin-embedded kidney tissue slices were prepared with a standard protocol of deparaffinization and rehydration. Antigen retrieval was done with Tris-Buffered Saline 1X (1.0M, pH 7.4) at 95°C for 40 minutes. Tissue was washed with PBS/ 0.05% Tween 20 twice for five 5 minutes and blocked with 5% FBS and 0.2% gelatin for 30 minutes. Then, the tissue was stained with 10 µg/ml of Purified anti-CD243 (Clone UIC2) overnight at 4°C. On the next day, tissue was washed twice with PBS and stained with Alexa Fluor® 594 goat anti-mouse IgG antibody (Clone POLY4053, red) for an hour at room temperature. Nuclei were counter-stained with DAPI (blue). The image was scanned with a 10X objective and stitched with MetaMorph® software.

CD243 (MDR-1) belongs to the ATP binding cassette (ABC) transporter family. With an approximate molecular mass of 170 kD, it consists of two homologous halves. Each half contains two hydrophobic transmembrane domains (TMDs) and two hydrophilic nucleotide binding domains (NBDs). The TMDs span the membrane six times, forming a chamber with a 12 transmembrane α-helix structure. NBDs drive the transport process through ATP coupling and hydrolysis and are located at the cytoplasmic face of the membrane. CD243 transports various molecules across cellular membranes and is involved in multidrug resistance. MDR-1 is expressed on hematopoietic stem cells, T cells, B cells, and NK cells as well as on many multidrug resistant neoplastic cells. CD243 interacts with Caveolin, RING finger protein 1B, AAP1, p53, Orphan nuclear receptor PX, and cytochrome P450.

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.5 µg per million cells in 100 µl volume.For immunohistochemical staining on formalin-fixed paraffin-embedded tissue sections, the suggested use of this reagent is 5.0 - 10 µg per ml. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Additional reported applications (for the relevant formats) include: blocking the efflux of fluorescent dyes1,2, immunoprecipitation1, and immunohistochemical staining of tissue sections of squamous cell carcinoma3.
