Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to
worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting
immunostaining in relation to complex human pathologies.
TCR Screening Services
Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding.
Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".
Rabbit Polyclonal (IgG) to Human Beta Galactosidase
IHC - Paraffin, Western blot
Rabbit Polyclonal to E. coli Beta Galactosidase
IHC, Western blot, ELISA
E. coli Beta Galactosidase
E. coli (tested or 100% immunogen sequence identity)
Delipidated and defibrinated
Western blot (1:500 - 1:2000)
Specificity and Use
Beta Galactosidase (E. coli).
Assay by immunoelectrophoresis resulted in a single precipitin arc against purified and partially purified Beta Galactosidase [E. coli]. Cross reactivity against Beta Galactosidase from other sources may occur but have not been specifically determined.
Suitable for immunoblotting (western or dot blot), ELISA, immunoprecipitation and most immunological methods requiring high titer and specificity.

2,000 µl deionized water
Short term 4°C, long term aliquot and store at -20°C, avoid freeze thaw cycles.
Anti-B-Galactosidase Antibody - Western Blot. Western blotting using Fluorescein conjugated anti-b-Galactosidase antibody shows a band at ~117 kD (lanes 1 - 3) corresponding to 60 ng, 30 ng and 15 ng, respectively of b-Gal present in partially purified preparations (arrowhead). Lane 4 shows no cross reactivity with proteins present in a non-specific control E. coli lysate. Proteins were resolved on a 4-20% Tris-Glycine gel by SDS-PAGE and transferred to nitrocellulose and blocking using Blocking Buffer for Fluorescent Western Blot. The membrane was probed with fluorescein conjugated anti-b-Galactosidase ( diluted to 1:10000. Reaction occurred for 2 hours at room temperature. Molecular weight estimation was made by comparison to a prestained MW marker in lane M. Fluorescence image was captured using the VersaDoc Imaging System developed by BIO-RAD. Other detection systems will yield similar results.
