Q: I purchased an antibody from Agrisera and need some technichal guidance. What should I do?
| Most common reasons why the desired result can not be obtained with a given antibody: Wrong antibody was purchased. Sequence used to elicit an antibody, is not found in the protein which is to be visualized. The sample contains too little of the target protein. For proteins of low abundance, the specific cellular fraction needs to be analyzed. The sample was not harvested in conditions, in which the target protein is most abundant in the tissue, or the extraction buffer was not optimal (for example: no specific protease or proteasome inhibitors were included). Antibody was incubated for too short time. Always check the product information sheet for guidance, or contact the supplier.  |
How to choose the right antibody? |  The poster can be downloaded here , or a hard copy can be requested on Agrisera website. View other educational posters focused on photosynthesis and epigenetics, here. Graphical work has been done by Dr. Dmitri Shevela, from SciGrafik in Umeå, Sweden. |

| With millions of catalog antibodies available, the antibody product datasheets should be carefully analyzed, in terms of specific validation data, before choosing an antibody for your experimental setup. Poor antibody validation contributes substantially to the ongoing reproducibility crisis. There is a lack of universal guidelines in antibody validation, as well as in how antibodies should be cited in scientific publications. In a recent Editorial Article published by Biocompare, tilted: "Advanced Antibody Validation Strategies to Ensure Scientific Reproducibility" many important aspects of the antibody validation process were covered, and discussed by experts in the field. The interviewees were:
Article excerpt to pay specific attention to: Another common validation strategy involves Western blot detection of the recombinant protein. However, Porankiewicz Asplund cautions that this can be misleading if the antibody datasheet is not read carefully. "Based on this type of data, researchers might expect to see a very intense band on a Western blot, not realizing that it is impossible to achieve this in an endogenous extract, for a target of low abundance," she says. Protein abundance can be easily checked in PaxDb. Read full article! |  What information to look for before purchasing an antibody? |
| While the technique of expansion microscopy (ExM) is commonly used in animal cells and tissues, plant-specific protocols are very few. However, the interest in this technique is growing, and Agrisera antibodies were recently applied in ExM on Arabidopsis thaliana primary roots. Using this method, called ROOT-ExM, the authors successfully imaged various organelles and subcellular compartments, including Golgi apparatus, the endoplasmic reticulum, the cytoskeleton and plasmodesmata. ExM opens new avenues for discoveries in studies of plant cells on the molecular level, as it circumvents the resolution limitations of traditional microscopy methods, and allows the revealing of finer details of cellular structures. Read the recently published article "Root expansion microscopy: A robust method for super resolution imaging in Arabidopsis". Cited Agrisera antibody: • SUN1,2 | SUN domain-containing protein 1,2 |  Agrisera polyclonal antibody to SUN1,2 | SUN domain-containing protein 1,2 (AS18 4224) was applied to visualize SUN1,2 protein using expansion microscopy (ExM) in Ar. thaliana roots. Details of the method are described here. |
| While the technique of expansion microscopy (ExM) is commonly used in animal cells and tissues, plant-specific protocols are very few. Agrisera's collaboration partner, Dr. Kirk Czymmek (Danforth Plant Science Center, USA) and his colleagues from several other American institutions, recently published a method that allows nonoscale imaging by physical expansion of fixed plant protoplasts in a swellable hydrogel. This method, called ExPOSE, leads to enhancement of the resolution by several folds, and shows that, combined with other imagining techniques, like immunofluorescence and in situ hybridization chain reaction, it can lead to visualization of proteins and mRNAs with enhanced spatial resolution. ExPOSE opens new avenues for discoveries in studies of plant cells on the molecular level, as it circumvents the resolution limitations of traditional microscopy methods, and allows the revealing of finer details of cellular structures. Read the recently published article "ExPOSE: a comprehensive toolkit to perform expansion microscopy in plant protoplast systems". Cited Agrisera antibodies: • Anti-GDC-H | H protein of glycine decarboxylase complex (GDC) (AS05 074) • Anti-ACT | Actin (polyclonal) (AS13 2640) • Donkey anti-Rabbit IgG (H&L), DyLight® 594 conjugated, pre-adsorbed (AS12 2076) |  Agrisera polyclonal antibody to plant actin (AS13 2640) was applied to visualize actin filaments using expansion microscopy (ExM) on Arabidopsis thaliana protoplasts.

In celebration of Agrisera’s 40th anniversary in 2025, we have conducted a series of short interviews with scientists, who have shared their knowledge, ideas and laboratory experience, contributing to the development of Agrisera's antibody collection for plant and algal science. The aim is to honor their contributions to the field, as well as inspire others to venture into plant science, with the support of Agrisera antibodies.
Dr. Douglas Campbell was a postdoctoral fellow at Umeå Plant Science Centre, in the group of Prof. Gunnar Öquist. He later held the position as Canada Research Chair in Phytoplankton Ecophysiology at Mount Allison University for over two decades, and is also Founder and Consulting Scientist at Environmental Proteomics NB. Agrisera has collaborated with Prof. Campbell over many years, including in the development of our collection of widely cited, so-called "global" antibodies.
- Please tell us about yourself and your research/institution.
- What motivated you to get into plant science?
My family had a background in agriculture and gardening, and I enjoyed working with plants. Around 1992 I transitioned to working primarily on cyanobacteria, because at the time molecular tools were more accessible for bacteria, than for plants. I then worked on most of the major lineages of eukaryotic phytoplankton, usually on questions related to photosynthesis and stress.
- How have you used (Agrisera) antibodies in your research?
Starting in 2002, we collaborated with Agrisera to design, test and launch lines of "global" antibodies, and accompanying quantitation standards. There is vast taxonomic and functional diversity across phytoplankton and plant groups, but most of their core metabolic pathways include very highly conserved proteins. So antibodies directed against conserved peptide regions can be used to detect and quantify major indicator proteins on an even basis, across a wide range of target organisms, and even in total protein extracted from mixed environmental samples. This allowed a single antibody + standard pair to be more widely used, covering the economic and personnel costs, while providing protein detection systems to groups who could not justify the costs of organism-specific antibodies. My own group has used antibodies produced through Agrisera in dozens of publications on dozens of organisms and systems.
- Any further comments?
Meeting Dr. Joanna Porankiewicz-Asplund, and then Greger Nordlund, of Agrisera was transformative to my career. Their confidence in funding the initial production of Global Antibodies led to a long and fruitful collaboration, with the resulting antibodies and standards now cited in thousands of diverse publications from around the world. I am grateful to Agrisera.
