(anti-Human and others as indicated)
RDI Divison of Fitzgerald Industries Intl offers a wide line of antibodies. Since no one antibody works best for all applications (neutralization, blotting, histochemistry, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.
Rabbit ANTI-HUMAN CYP4A11 IgG
Polyclonal Antibody Developed in Rabbits
Antiserum was developed in rabbits using purified human liver CYP4A11 as immunogen. The whole IgG fraction was purified from antiserum using caprylic acid/ammonium sulfate fractionation. Anti-human CYP3A4 IgG is provided as a 10 mg/ml solution in 100 mM potassium phosphate buffer (pH 7.4), 250 mM KCl, and 2.5 µM thimerosal (added as a preservative), or as a powder lyophilized from this buffer.
¨ Specificity and Purity
Specificity has been determining by Western blotting. Anti-human CYP4A11 IgG reacts exclusively with its corresponding 53 kDa antigen in human liver microsomes. In addition, the antibody recognizes the homologous CYP4A proteins in rat liver microsomes. Specificity with whole liver homogenates or S-9 fractions has not been determined. Purity of the antibody has been established by SDS-PAGE run under denaturing conditions. Two protein bands with molecular weights of 50 kDa and 25 kDa can be visualized by Coomassie blue staining, which correspond to the heavy and light chains, respectively, of rabbit IgG.
¨ Reconstitution and Storage
Reconstitute by adding 0.5 ml of distilled water to one vial of lyophilized IgG (1 mg). Rotate vial gently until powder dissolves. Add 0.5 ml of neat glycerol to obtain a 50% glycerol solution containing 1 mg IgG/ml. Prior to reconstitution, store the product at 0-5°C. After reconstitution, the solution can be stored at -20°C since the presence of 50% glycerol will prevent freeze/thaw cycles. Anti-CYP4A11 IgG solutions without glycerol should also be stored at -20°C but should be freeze/thawed as little as possible.
Immunoreactivity of Anti-CYP4A11 IgG with human liver proteins
Lane A = UC9411 microsomes (10 µg)
Lane B = UC9402 microsomes (10 µg)
Lane D = Purified CYP4A11 (0.1 µg)
Lane B = UC9406 microsomes (10 µg)
¨ Use for Western Blotting
1. For full size (15 x 15 cm) blots, add 200 µg rabbit anti-human CYP4A11 IgG to 15-20 ml of blocking solution (e.g., Blotto). This corresponds to 200 µl of the 1.0 mg IgG/ml solution prepared in 50% glycerol as described above. The amount can be scaled down proportionally with smaller size blots.
2. Incubate overnight at room temperature, and remove antibody solution (which can be stored at -20°C for re-use). After washing blot extensively with blocking solution to remove unbound CYP4A11 antibody, incubate with an anti-rabbit IgG conjugate of choice (e.g, anti-rabbit IgG peroxidase, anti-rabbit IgG-alkaline phosphatase or anti-rabbit IgG-biotin), and stain accordingly.
Note:we recommend titering for each use (ie, use of enhanced chemiluminescence detection systems may allow greater dilution of the antibody).
Precaution: For in vitro research use only-not for use in or on humans or animals-not for use in diagnostics. Not responsible for any patent infringements with the use or derivation of these products.
