Overview

Product name

Anti-Islet 1 antibody - Neural Stem Cell Marker
See all Islet 1 products (6) ...

Description

Rabbit polyclonal to Islet 1 - Neural Stem Cell Marker

Specificity

ab20670 might also detect rat and human Islet 2 protein as the immunogen used to raise this ab20670 is 86% identical to rat and human Islet 2. This has not been tested.

Tested applications

IHC-FoFr, IF, IHC-P, ICC/IF, IHC-Frmore details

Cross reactivity

Reacts with

Mouse, Rat, Human, Apteronotus leptorhynchus

Predicted to work with

Chicken, Zebrafish

Immunogen

Synthetic peptide conjugated to KLH derived from within residues 300 to the C-terminus of Human Islet 1.

(Peptide available as ab21996.)

Positive control

4 day old cultures of rat dorsal root ganglion neurons (16 day old rat embryos).

  Immunocytochemistry/ Immunofluorescence

Immunocytochemistry/ Immunofluorescence

Dorsal root ganglion explants were dissected from 16 day-old rat embryos and cultured for 6 hours in vitro with Neurobasal Medium containing B27 supplement.     

Nuclei stained positive for anti-Islet 1 antibody ab20670 at 2µg/ml. As would be expected, not all cells in this preparation were Islet 1-positive. Pre-incubation of ab20670 with the immunizing peptide ab21996 resulted in complete blocking of the antibody.

  Immunohistochemistry (Frozen sections) - Islet 1 antibody - Neural Stem Cell Marker (ab20670)

Immunohistochemistry (Frozen sections) - Islet 1 antibody - Neural Stem Cell Marker (ab20670)

ab20670 detected Islet 1 in the nucleus of frozen sections of E11.5 mouse embryonic brain using 1 ug/ml of antibody. Brighter staining may be achieved using a greater concentration of antibody, e.g. 2.5 or 5 ug/ml.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections)-Islet 1 antibody - Neural Stem Cell Marker(ab20670)

ab20670 2µg/ml staining ISLET1 in human pancreas using an automated system (DAKO Autostainer Plus). Using this protocol there is strong nuclear and weak cytoplasmic staining primarily in the pancreatic islet.
Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
