    C57BL/6 mouse frozen spleen section was fixed with 4% paraformaldehyde (PFA) for 10 minutes at room temperature and blocked with 5% FBS for 30 minutes at room temperature. Then the section was stained with 10 µg/ml of GL7 (clone GL7) purified, CD3 (clone 17A2) Alexa Fluor® 647 (green) and B220 (clone RA3-6B2) Alexa Fluor® 488 (blue) overnight at 4°C, followed by 2.5 µg/ml of anti-rat IgM (clone MRM-47) Biotin for 2 hours, followed by 2.5 µg/ml of Streptavidin Alexa Fluor® 594 (red) for 2 hours at room temperature. The image was captured by 10X objective.

Description

The GL7 antigen, also known as Ly77, is a 35 kD protein.  The GL7 antigen has an epitope containing non-sulfated α2-6-sialyl-LacNAc recognized by the GL7 antibody. The GL7 antigen is expressed by pre-B and immature B cells, activated T and B cells, and about 20% of TCR-bright thymocytes.  It is upregulated on mouse splenocytes following activation.  It may play a role in regulation or adhesion.  GL7 high-expressing B cells show higher antibody production and antigen presenting capacity.

Application

FC - Quality tested
ELISA, IHC-F, IP - Reported in the literature, not verified in house
Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.5 µg per million cells in 100 µl volume. For immunohistochemical staining on frozen tissue sections, the suggested use of this reagent is 2.5 - 5.0 µg per ml. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

The GL7 antibody does not block the binding of CD22 with sulfated a2-6-sialyl-LacNAc.

Cross-reactivity to ferret has been reported by a collaborator, but not verified in house.
