Features & Benefits
Human Ras-related protein Rab-37 (RAB37) ELISA Kit has high sensitivity and excellent specificity for detection of Human RAB37. No significant cross-reactivity or interference between Human RAB37 and analogues was observed.
Background
Using yeast 2-hybrid analysis with mouse Rab5 as bait, Masuda et al. (2000) identified Rab37 from a mouse mast cell line. The deduced Rab37 protein contains sequence motifs conserved in other low molecular mass GTPases.
It shares 74% and 47% amino acid sequence identity with rat RAB26 and mouse Rab8 (RAB8A). Northern blot analysis showed expression of 2.3- and 1.2-kb Rab37 transcripts exclusively in the MC9 mast cell line. Immunoprecipitation followed by Western blot analysis of a panel of mouse tissues showed that a 34-kD band corresponding to the Rab37 protein is expressed exclusively in bone marrow mast cells. Expression of GFP-tagged Rab37 in bone marrow mast cells showed that Rab37 localizes to secretory granules.
This Ras-related protein Rab-37 (RAB37) ELISA kit is validated for use with Cell culture supernatants, Serum, Plasma, Other biological fluids. Samples should be collected, processed, and stored correctly to preserve analyte integrity — avoid repeated freeze-thaw cycles and centrifuge to remove particulates before use. Dilute samples exceeding the kit's detection range using the supplied assay diluent. Hemolytic, icteric, or lipemic samples may affect assay performance and should be tested with caution.
This is a sandwich ELISA kit employing an HRP (horseradish peroxidase)-conjugated secondary antibody paired with a TMB (3,3′,5,5′-tetramethylbenzidine) colorimetric substrate. In the sandwich format, the target analyte Ras-related protein Rab-37 (RAB37) captured on the microplate surface is detected by the conjugated antibody, generating a colorimetric signal proportional to analyte concentration. The reaction is stopped and absorbance measured at 450 nm on a standard microplate reader.
The complete protocol, from sample addition to final plate reading, requires approximately 3–5 hours. This includes two incubation periods (analyte binding and detection antibody steps), intermediate wash cycles to remove unbound material, 15–30 minutes of TMB substrate development, and final stop-solution addition before absorbance reading. Exact timing will vary with experience level and the number of samples processed in parallel.
Required equipment: (1) a microplate spectrophotometer capable of reading absorbance at 450 nm (reference wavelength 540–570 nm recommended for background correction); (2) precision single-channel or multichannel pipettes; (3) a plate washer or multichannel aspirator; (4) a microcentrifuge for sample clarification; and (5) a 37°C incubator or stable room-temperature environment. No fluorescence or luminescence reader is required — standard colorimetric plate readers are fully compatible with this kit.
This ELISA kit is formally validated for Human. Cross-reactivity with species not listed in the specification has not been independently characterized. Variability in protein sequence homology across species means that performance in unlisted species cannot be guaranteed without additional validation.
