(anti-Human and others as indicated)

RDI Divison of researchd 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.

Category                 Rabbit polyclonal

Form/Purification   Undiluted rabbit serum (lyoph.)

Immunogen            Synthetic human ß-Endorphin (Peninsula)

Description/Specificity ß-endorphin occurs in ACTH- and MSH-cells of the pituitary. It occurs also in scattered cells in the adrenal medulla and in nerves of the brain and gut. ß-endorphin may occur in tumors of the pituitary, bronchial and gastrointestinal carcinoids.

Rabbit anti-beta-Lipotropin

cat# RDI-BLIPOTabr   $375.00

Presentation: 50ul lyophilized with 0.1% sodium azize as a preservative

Immunogen: N-terminal portion of bovine species beta-Lipotropin conjugated to thyroglobulin

Species Reactivity: Rat, Mouse, Human (0thers not tested)

Cross Reactivity: beta-Lipotropin 100

                            Met-enkephalin 0.01

                            Leu-enkephalin 0.01

                             beta-Endorphin 0.01

Storage: This product is diluted hyper-immune antiserum that has been lyophilized from a solution containing 0.1% sodium azide as a preservative. It is recommended to store this antiserum at 0-4 o C prior to reconstitution. Reconstitute vial (50 ug) with 50 uL of distilled water, divide into aliquots and store frozen at -20 o C or lower. Avoid repeated freezing and thawing. Frozen aliquotes can be stored for at least six months. For better performance, once a frozen aliquot has been thawed, make a working dilution (antibody dilution buffer should contain 0.1% of sodium azide) and keep it at 0-4 o C (stable for at least 1 month).

Use: Immunohistochemistry: For slide-mounted tissue sections it is recommended to make working dilution for immunofluorescence histochemistry is 15 ug/ml, whereas for avidin-biotin immunohistochemistry antiserum may be diluted to 5 ug/ml.

Immunofluorescence: Dilute antibodies with 0.1M phosphate buffered saline (PBS, pH 7.4) containing 1% bovine serum albumin and 0.01 Triton X-100. Incubate sections for 24-48 hours in a cold room. Wash in PBS (15 min x 3). Incubate for 1 or 2 hours at room temperature with donkey anti-rabbit secondary antibodies conjugated to fluorescent probes (FITC,LRSC; Cy 3, Cy 2, Cy5 - . Wash in PBS (15 min x 3) and mount under coverslips using mediums reducing fading of fluorophores (e.g. SlowFade Molecular Probes). If stained using cyanin fluorophores, sections can be dehydrated in grading alcohols (50%, 75%, 80%, 96% and 100%), cleared in xylene and mounted with DPX (for

reference see a catalogue of Fluka, Ronkonkoma, NY). Staining can be visualized by using both conventional and confocal microscopy. Indirect immunostaining technique: Incubate sections with 0.3% H2O2 in PBS for 15 minutes at room temperature to block endogenous peroxidase. Rinse sections with PBS (three times for 10 minutes), incubate sections overnight at +4oC and then wash in PBS (three times for 10 minutes). Incubate sections with biotinilated goat anti-rabbit secondary antibodies diluted in accordance with manufacturers recommendations in PBS (do not add sodium azide!) for 1 hour at room temperature, rinse sections three times for 15 minutes and incubate sections with ABC reagent (Vector Laboratories) at room temperature for 30 minutes. Rinse sections in PBS and incubate them in substrate solutions (e.g. DAB, AEC or VIP - - Vector Laboratories) to achieve necessary intensity of Endomorphin-1 staining.
