Technical Info

F(ab')2 fragment antibodies are generated by pepsin digestion of whole IgG antibodies to remove most of the Fc region while leaving some of the hinge region. F(ab')2 fragments have two antigen-binding Fab portions linked together by disulfide bonds and therefore they are divalent. The average molecular weight is about 110 kDa. They are used for specific applications, such as to avoid binding of secondary antibodies to live cells with Fc receptors or to Protein A or Protein G.

Based on immunoelectrophoresis and/or ELISA, the antibody reacts with whole molecule rat IgG. It also reacts with the light chains of other rat immunoglobulins. No antibody was detected against non-immunoglobulin serum proteins. The antibody has been tested by ELISA and/or solid-phase adsorbed to ensure minimal cross-reaction with bovine, chicken, goat, guinea pig, syrian hamster, horse, human, mouse, rabbit and sheep serum proteins, but it may cross-react with immunoglobulins from other species.
Physical State: Freeze-dried solid

Storage and Rehydration: Store freeze-dried solid at 2-8°C. Rehydrate with the indicated volume of dH2O and centrifuge if not clear. Store at 2-8°C – do not freeze. Prepare working dilution on day of use.
Expiration date: six months from date of rehydration. The expiration date may be extended if test results are acceptable for the intended use.


Purity: The antibody was purified from antisera by a combination of pepsin digestion and immunoaffinity chromatography using antigens coupled to agarose beads. Fc fragments and whole IgG molecules have been removed.
Buffer: 0.01M Sodium Phosphate, 0.25M NaCl, pH 7.6
Stabilizer: 15 mg/ml Bovine Serum Albumin (IgG-Free, Protease-Free)
Preservative: 0.05% Sodium Azide

Suggested Working Concentration or Dilution Range:
Flow Cytometry:- 1:25-1:100

Dilution factors are presented in the form of a range because the optimal dilution is a function of many factors, such as antigen density, permeability, etc. The actual dilution used must be determined empirically.

PerCP

Amax: 488 Emax: 675nm

PerCP is a fluorescent peridinin-chlorophyll-protein complex isolated from dinoflagellates. We offer the form found in Dinophyceae sp. with a molecular weight of about 35.5 kDa. It has a broad spectrum of excitation with a main peak at 482 nm, and a long Stokes shift to an emission peak at 677 nm. 

PerCP, Alexa Fluor® 488 (or FITC), and R-PE are excited at 488 nm with an argon laser, and thus can be used for one-, two-, and three-color analyses with single-laser flow cytometers. APC and Alexa Fluor® 647 are excited at 633 nm to give a fourth color with dual-laser flow cytometers. 

PerCP is also highly water soluble, has a relatively low isoelectric point, and lacks potentially sticky carbohydrates.

It should be noted that the relatively high molecular weight of PerCP may preclude its use in procedures requiring good penetration into cells and tissues. It is predominantly intended for surface labeling of cells for flow cytometry.
