NewBlot IR Stripping Buffer is ideal for stripping and reprobing nitrocellulose and PVDF membranes detected with IRDye® secondary antibodies. It may also be suitable for other dye-conjugated secondary antibodies.

NewBlot IR Stripping Buffer is not recommended for loading amounts over 30 µg.

This robust reagent removes primary and secondary antibodies while maintaining target antigen integrity for efficient reprobing and does not require hazardous shipping, unlike many other stripping buffers.

Note: NewBlot IR Stripping Buffer is provided as a '5X' concentrated solution.


Strip and reprobe nitrocellulose or PVDF membranes

Figure 1. Strip and reprobe nitrocellulose or PVDF membranes effectively with NewBlot IR Stripping Buffer. EGFR and phospho-ERK levels were compared in EGF-stimulated (+) and non-stimulated (-) A431 lysate (1 µg total protein). The membrane was probed with mouse anti-EGFR, mouse anti-pERK1/2, and β-tubulin rabbit polyclonal (LI-COR P/N 926-42211), then detected with IRDye 800CW Goat anti-Mouse (LI-COR P/N 926-32210) and IRDye 680RD Goat anti-Rabbit (LI-COR P/N 926-68071). The blot was scanned with an Odyssey® CLx Imaging System (Original blot). The blot was then stripped with NewBlot IR Stripping Buffer (LI-COR P/N 928-40028), and scanned again (Strip #1). The blot was detected with the same primary and secondary antibodies and scanned again (Reprobe #1). The process was repeated 2 more times (Strip and Reprobe #2-3). Image display settings for all stripped and reprobed images are identical to the original image.
