(2022) Blind spots on western blots: Assessment of common problems in western blot figures and methods reporting with recommendations to improve them. Additional resources include a toolbox to help scientists produce more reproducible western blot data, teaching slides in English and Spanish, and an antibody reporting template.Ĭitation: Kroon C, Breuer L, Jones L, An J, Akan A, Mohamed Ali EA, et al. We present detailed descriptions and visual examples to help scientists, peer reviewers, and editors to publish more informative western blot figures and methods. Important antibody identifiers like company or supplier, catalog number, or RRID were omitted frequently for primary antibodies and regularly for secondary antibodies. Western blot methods sections often lack information on the amount of protein loaded on the gel, blocking steps, and antibody labeling protocol. Publishing blots with visible molecular weight markers is rare, and many blots additionally lack molecular weight labels. Our data show that most published western blots are cropped and blot source data are not made available to readers in the supplement. We systematically examined 551 articles published in the top 25% of journals in neurosciences ( n = 151) and cell biology ( n = 400) that contained western blot images, focusing on practices that may omit important information. While several groups have studied the prevalence of image manipulation or provided recommendations for improving western blotting, data on the prevalence of common publication practices are scarce. ![]() Unfortunately, poor western blot image display practices and a lack of detailed methods reporting can limit a reader’s ability to evaluate or reproduce western blot results. Novex AP Chemiluminescent Substrate should be combined with Nitro Block II for use with nitrocellulose membranes.Western blotting is a standard laboratory method used to detect proteins and assess their expression levels. The emitted light is stable up to 24-96 hours allowing for multiple exposures.Ĭhoose from a standalone substrate, Novex AP Chemiluminescent Substrate or the WesternBreeze Chemiluminescent Immunodetection kits which contains all solutions necessary for your application including blocking solutions, primary antibody diluent, ready-to-use secondary antibody solution, ready-to-use chemiluminescent substrate, wash solutions, incubation trays, pre-cut filter papers, polyester sheet for even substrate development on the membrane. Light emission occurs only during the enzyme-substrate reaction therefore, once the substrate in proximity to the enzyme is exhausted, signal output ceases. CDP-Star is dephosphorylated by AP to yield meta-stable dioxetane phenolate anion intermediate that decomposes and emits light with a maximum intensity at a wavelength of 475 nm. For western blot detection based on alkaline phosphatase (AP), 86 kDa, we offer our CDP-Star substrate that is designed to deliver picogram level sensitivity and is compatible with both traditional x-ray film and CCD-based imaging. ![]()
