What is the ELK0655 Human Bta Bladder Tumor Antigen Elisa Kit used for?
ELK0655 Human Bta Bladder Tumor Antigen Elisa Kit is a DNA ladder/marker used as a size reference during gel electrophoresis.
What fragment size range does it cover?
The fragment range depends on the ladder type (e.g., 100 bp, 1 kb). Confirm band sizes on the datasheet.
Which applications are supported?
Used for agarose or PAGE electrophoresis to estimate DNA fragment sizes in samples.
How do I use it on a gel?
Load the ladder in a dedicated lane. Compare sample bands to ladder bands to estimate size.
How should it be stored?
Store at -20°C. Thaw on ice and mix gently. Avoid repeated freeze–thaw cycles.
Is it ready-to-load?
Some ladders include loading dye; others require adding dye. Check the product documentation.
How do I get sharper bands?
Use appropriate agarose %, fresh buffer, correct voltage, and avoid overheating to reduce band distortion.
What controls should I include?
Run a known DNA fragment (positive control) if you need to verify gel performance and staining.
Is technical support available?
Yes—share gel conditions (agarose %, voltage, buffer, stain) for troubleshooting.
