Regulatory Status Legend
Allophycocyanin (APC), is an accessory photosynthetic pigment found in blue-green algae. Its molecular weight is approximately 105 kDa. APC has six phycocyanobilin chromophores per molecule, which makes it a very bright fluorochrome that is highly suitable for flow cytometry applications. Due to nearly identical excitation and emission properties but different spillover characteristics, APC and Alexa Fluor® 647 cannot be used simultaneously
Preparation and Storage
The polyclonal antibody was purified from antiserum by negative adsorption and affinity chromatography.
The antibody was conjugated to APC under optimum conditions, and unconjugated antibody and free APC were removed.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
The purified antibody solution was passed through solid-phase immunoadsorbent gels to minimize cross-reactivity with mouse, human, cow, and horse serum proteins.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.

- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
This antibody stains rat peripheral B cells, and it has little reactivity with rat non-B splenocytes or mouse splenocytes. As a second step, it is reactive with rat IgG and IgM monoclonal antibodies; a weaker signal is detected when the primary antibody has a rat IgG2b isotype. It has weak cross-reactivity detectable by flow cytometry with some, but not all, hamster immunoglobulins. Consequently, it may be useful as a primary reagent in immunofluorescent staining of rat antibody-producing cells or as a secondary reagent for staining of mouse leukocytes after reaction with rat Ig primary antibodies. However, we have observed that the reactivity of polyclonal second-step antibodies to mouse or rat IgM may be reduced after adsorption against Ig of rat or mouse, respectively. Because this anti-rat Ig antibody was adsorbed with mouse Ig, it may be weakly reactive with some rat IgM primary antibodies.
