Background
CD71 is specific for the human transferrin receptor, MW 190 kdaltons (kDa), 90 kDa reduced. CD71 antigen expression is low on normal resting lymphocytes and is expressed on all cells upon activation. The transferrin receptor is essential for iron transport into proliferating cells, such as mitogen-activated and alloantigen-activated lymphoblasts. The transferrin receptor is also present on early erythroid cells but is lost as reticulocytes differentiate into mature erythrocytes.

Synonyms: CD71

Source
Derived from the hybridization of mouse myeloma cells with spleen cells from BALB/c mice immunized with blast cells from pokeweed mitogen-stimulated peripheral blood cells.

Product
Provided as solution in phosphate buffered saline with 0.08% sodium azide

Product Form: Unconjugated

Applications
PBMC: Add10 µl of MAB/10^6 PBMC in 100 µl PBS. Mix gently and incubate for 15 minutes at 2º to 8ºC. Wash twice with PBS and analyze or fix with 0.5% v/v of paraformaldehyde in PBS and analyze.
