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. Please inquire for other applications or types of antibodies not listed below.

ANTI-Desmocollin 3
Mab to Desmocollin 3

cat#RDI-PRO65193      $375.00/vial

Clone:                            Dsc3-U114

Category:                       Mouse monoclonal

Immunoglobulin Class:     IgG1

Form/Purification            Cell culture supernatant

Antigen:                         Synthetic peptide corresponding to a sequence present on the extracellular anchor domain of                                                 human desmocollin 3. (VHGAPFYFSLPNTSPEISRLWSLTKVBC).

Clinical Application/

Specificty:                       Mab localizes Dsc3 present in · all living epidermal layers · in glandular duct cells

                                       · in basal matrix cells and outer root sheath of hair follicles

                                       · basal and suprabasal cell layers of stratified epithelia (e.g. vagina, tongue, esophagus), basal

                                         layer of bladder urothelium and complex epithelium of trachea · thymic reticulum cells

All simple epithelia are negative. Intercalated disks of myocardium are negative.

Reactivities on Cultured Cell Lines: Most cultured cell lines derived from stratified squamous epithelia or squamous cell carcinomas are positive (e.g. A-431, HaCaT).

Application Suitable for · immunohistochemistry on frozen and paraffin- embedded sections

                                    · immunoblotting (Western)

Recommendations: For better results on frozen sections, preincubation (directly after fixation) with 0.05- 0.2% Triton X100, for 5-10 min, depending on tissue type, is recommended. SEE REF#2.

Storage At 4°C

Volume 5 ml
