  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use

CD4 antibody was raised against nS0-derived rfeCD4 extracellular domain.
Feline CD4 extracellular domain.
In direct ELISAs and Western blots, this antibody shows approximately 25% cross-reactivity with rcaCD4, and. 5% cross-reactivity with rhCD4 and rmCD4. Applications. Western blot-This antibody can be used at 0.1-0.2 µg/ml with the appropriate secondary reagents to detect feline CD4. The detection limit for rfeCD4 is approximately 1 ng/lane and 5 ng/lane under non-reducing and reducing conditions, respectively. Immunocytochemistry-This antibody will detect CD4 in cells. The working dilution is 2-15 µg/ml. Flow Cytometry-This antibody has been tested on T-cells for use in flow cytometry. Dilute this antibody to 50 µg/ml and add 10 ul of the diluted solution to 1-2.5 x 105 cells in a total reaction volume not exceeding 200 ul. The binding of unlabeled antibodies may be visualized by adding 10 ul of a 25 µg/ml stock solution of a secondary developing reagent such as anti-goat IgG conjugated to a fluorochrome. Direct ELISA-This antibody can be used at 0.5-1.0 µg/ml with the appropriate secondary reagents to detect feline CD4. The detection limit for rfeCD4 is approximately 0.3 ng/well.


Lyophilized from 0.2 µm filtered 100 mM NaHCO3, pH 8.3, 500 mM NaCl, 1% sucrose.
Store at -20°C.

CD4 Antibody, CD4 antigen Antibody, CD4 receptor Antibody, CD4mut Antibody, CD4 antigen (p55) Antibody, CD4 molecule Antibody

CD4 is a membrane glycoprotein of T lymphocytes that interacts with major histocompatibility complex class II antigenes and is also a receptor for the human immunodeficiency virus. This gene is expressed not only in T lymphocytes, but also in B cells, macrophages, and granulocytes. It is also expressed in specific regions of the brain.
