RDI Divison of Fitzgerald Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, 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.

see below 2 polyclonals
Polyclonal Antibody to Peptide YY (PYY)

Cat#RDI-PRO11431     $375.00

Category                        Rabbit polyclonal

Purification/Form         Rabbit serum

Immunogen                    Human PYY

Specificity                   The intestinal peptide YY occurs in glicentin cells in the gut. They are found in the rectum, colon, ileum, and to a lower extend in the duodenum and jeju-num. PYY occures in endocrine tumors of the pan-creas and the rectum.

Application                 · Immunohistochemistry

                                  · Suitable for frozen and paraffin-embedded tissue

                                   (No protease pretreatment required)

Positive Control         Colon, ileum

Reactivity with Species: Human, rat, cat

Dilution Buffer                 0.15 M PBS with 1% BSA and 0.1% NaN3

Working Dilution             1:50 - 1:100 in immunohistochemistry

Storage                             At 2-8°C in undiluted form; for longer periods ali-quots should be stored at -20° C

Volume                            0.25 ml

For In Vitro Research Use Only

Guinea Pig Polyclonal Antibody to PYY (Peptide YY)

Cat#RDI-PRO16066  $562.00/vial

Category                     Guinea pig polyclonal

Form/Purification        Undiluted guinea pig serum (lyoph.)

Immunogen                   Synthetic porcine peptide YY (Peninsula)

Description/Specificity The intestinal peptide YY is related to the PP-family of peptides and occurs in the glicentin cells in the gut. They are numerous in the rectum, colon, and ileum and few in the duodenum and jejunum. PYY has hormone-like action, inhibits gut motility and pancreatic exocrine secretion and cause vasoconstriction. PYY may occur in endorine tumors of the pancreas and of the rectum. Absorption with 10-100 µg immunogen per ml diluted antiserum abolishes the staining.

Positive Control            frozne sectiosn of rat intestine or Bouin-fixed paraffin sections of cat small intestine

Species tested so far      rat, Cat, mouse

Application · Immunohistochemistry

                     · Suitable for frozen and paraffin sections

Reconstitution Dissolve the antiserum in 50 - 100 µl distilled water, and dilute further in 0.1 M PBS with 1% BSA and 0.1% NaN3.

Working Dilution 1:400 - 1:800 for immunohistochemistry (PAP) with overnight incubation at 2-8°C.

                             1:1500-1:2500 using FITC with overnigth incubation at 2-8 DEG C

Storage At 2-8°C (undiluted) or at -20°C (aliquots)

Quantity / Volume 50 µl (lyoph.)
