Native Human IgM gallery image 1 — Sandwich ELISA analysis of IgM binding using Mouse anti Human IgM antibody, clone M15/8 (MCA1662) as a capture reagent and biotinylated Goat anti Human IgM (AHP1764) as a detection regent with purified human IgM (**5275-5504**) as antigen for the generation of the standard curve. Subsequent detection is by HRP conjugated streptavidin and substrate. Microtitre plate is read at O.D. 450 nm on the Bio-Rad iMark Microplate Absorbance Reader (Bio-Rad Catalog 168-1135). Serum samples at 1:10k (green) and 1:100k (blue), similarly plasma samples 1:10k (orange) and 1:100k (red) dilutions are shown

Native Human IgM is purified from human plasma and demonstrated a single band in electrophoresis. Native Human IgM has been used as the IgM antigen in the development of a sensitive ELISA assay for the measurement of IgM in human samples.

Target Species: Human
Product Form: Purified immunoglobulin from human plasma - lyophilized
Reconstitution: Reconstitute with 1ml 250mM Sodium Chloride. Further dilutions may then be made in sterile Phosphate Buffered Saline.
Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution.
Preparation: Purified IgM prepared by delipidation, salt fractionation and ion-exchange chromatography.
Buffer Solution: Phosphate buffered saline.
Preservative Stabilisers: None present.
Purity: >95% Single band in high resolution protein electrophoresis on Corning HRPE agarose gel. 0.5 ?l of IgM solution at 50 mg/ml in isotonic saline.
Approx. Protein Concentrations: 5.0 mg/ml after reconstitution
Regulatory: For research purposes only
Guarantee: 12 months from date of despatch

Store at -20^oC only.
Storage in frost-free freezers is not recommended.
This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the protein. Should this product contain a precipitate we recommend microcentrifugation before use.

This product has been reported to work in the following applications.
