Agrisera antibodies in immunolocalization studies overview

The conference Straub Days 2023, took place between 25th and 26th of May at the Biological Research Centre, Szeged, Hungary. During the conference, the poster "Plant cell immunolocalization and the use of advanced imaging techniques at HCEMM Advanced Core Facility" was presented by Dr. Ferhan Ayaydin and Dr. Divya Teja Dondapati from the Functional Cell Biology and Immunology-Advanced Core Facility, HCEMM, Szeged; and Institute of Plant Biology, BRC, Szeged.

The poster showed various methods of material preparaton, and included immunolocalization results obtained with Agrisera antibodies to:

Actin (AS22 4615)
Clathrin heavy chain 1,2 (AS10 690)
Histone 3 (AS10 710A), and
GFP (AS21 4443)

These were combined with matching Agrisera secondary antibodies:

Donkey anti-mouse IgG (H&L), DyLight® 488-conjugated secondary antibodies (AS10 1261), and
Donkey anti-Rabbit IgG (H&L), DyLight® 550-conjugated secondary antibody (AS12 1962)

The plant material used were: Oryza sativa L. ssp. japonica cv. 'Unggi 9', Zea mays hybrid variety, Arabidopsis thaliana expressing GFP, and Oryza sativa bpt-jeelakarra variety.

Sample preparation methods followed for the immunolocalization studies on dicot and monocots were: suspension culture, root squash, whole root mount and cryosectioning.

Fast and easy protein extraction using Agrisera Protein Extraction Buffer (PEB)

Protein Extraction Buffer (PEB) is an extraction buffer for the disruption and solubilization of total protein from plant tissues and algal cells. The buffer contains the anionic detergent LDS, which does not form crystals while stored at 4-10°C, and is quickly ready to use.

Expected yields will be 1.5-6 µg/µl total protein (recovered from standard procedure), depending on the starting material, e.g. its biological stage and homogenization method used (bead beater vs. sonication). For processing of multiple samples, simultaneous extraction using for example a bead beater is recommended, for consistency of extraction.

Provided as 5 x 2 ml (4x stock), Agrisera's PEB buffer allows up to 75 isolations of plant material (using 500 μl 1x PEB for 100 mg fresh weight), or 190 isolations of algal material (using 200 μl 1x PEB for cell amounts corresponding to 4-10 μg total chlorophyll).

Agrisera Western blot training for Bicom, Agrisera distributor in South Africa

On the 26th of May, Dr. Joanna Porankiewicz Asplund, Technical Support Manager at Agrisera, conducted a Western blot training for the sales force of Agrisera's distributor in South Africa, Bicom Biotech.

The aim was to show which are the most crucial steps of Western blot, and how to help customers using this widely employed protein analysis technique.

Good luck with helping your customers succeed with their Western blots!

Extensive collection of antibodies to Arabidopsis thaliana proteins involved in a stress response

As climate change becomes more noticeable, and affect all life on Earth, research on how plants respond to environmental stress intensifies in many laboratories worldwide. Agrisera antibodies, to key proteins involved in plant stress response, help solve many pressing questions of how plants tackle changes to, and threats in, their environment. New antibodies are added continuously to our collection, which includes antibodies to proteins involved in:

Cold stress | Drought stress | Heat shock | Heavy metals | Hypoxia | Oxidative stress | Pathogen attack | Salt stress | UV radiation | Wounding

Agrisera Western blot workshop for Wageningen University & Research Laboratory of Biochemistry

On the 15th of May, Dr. Joanna Porankiewicz-Asplund, Agrisera's Technical Support Manager, conducted an online workshop for researchers from the Wageningen University & Research Laboratory of Biochemistry, The Netherlands. The title of the workshop was "Western blot - a technique possible to optimize".

The workshop was almost two hours long, including a 10 minutes break for the Agrisera Antibody and Western blot Quizzes and coffee. Questions submitted by attendees were answered, and many pitfalls of the Western blot technique were discussed, with specific experimental examples.

Participants also had a chance to win Agrisera high titer secondary antibodies and 2 ECL reagents, in two quizzes, consisting of questions about antibodies and the Western blot technique.

Each participant of the workshop received a pdf of the presentation with links to additional information, as well as a pdf of Agrisera's Western blot guide. The recording of the workshop is available on demand.

If you are interested in this type of online workshop to be held at your institution, please contact us!
