Application

This Anti-HLA-B27 Antibody, clone HLA.ABC.m3 is validated for use in FC, IC for the detection of HLA-B27.

This antibody is useful in the investigation of HLA-B27 in diseases such as ankylosing spondylitis and anterior uveitis.

SUGGESTED USAGE DILUTION

1. Flow cytometry and indirect immunofluorescence 1:60 to 1:120

Dilute with isotonic buffer. Use 50 µl of diluted antibody per 1 x 10E6 peripheral blood mononuclear cells (PBMC) in 100 µl buffer.

2. Cytotoxicity testing 1:25.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.

Physical form

The antibody is supplied in phosphate-buffered saline, pH 7.4, containing 0.2% bovine serum albumin and 0.1% sodium azide. The characteristics of each lot are tested by flow cytometry.

Format: Purified

Specificity

This antibody binds strongly to the HLA-B27 antigen. It also binds less strongly to the HLA-B7 antigen. Affinity studies by Scatchard analysis showed that the antibody has a higher affinity for HLA-B27 (9.7x108M-1) than for HLA-B7

(9.5x107M-1).

Cell reactivity:

Flow cytometric analysis of lymphocyte staining for HLA-B27 gave the following results:



Subjects Fluorescence Intensity

Heterozygous HLA-B27+ Strong

Homozygous HLA-B7+ Strong

Heterozygous HLA-B7+ Faint

Non B27, Non B7 Negative

Storage and Stability

Store at 2 to 8°C. For prolonged periods, store below -20°C in undiluted aliquots. AVOID REPEATED FREEZE/THAW CYCLES.

WARNING: The monoclonal reagent solution contains 0.1% sodium azide as a preservative. Due to potential hazards arising from the build up of this material in pipes, spent reagent should be disposed of with liberal volumes of water.
