Agrisera at Nordic Photosynthesis Congress and Algal Symposium in Ume

Agrisera participated in the Nordic Photosynthesis Congress and Nordic Algae Symposium, between the 19th and 21st of June, at Umeå University, Sweden. At the event there were 119 researchers present, and 32 posters covering this year's theme "From Photosynthesis to Industrial Applications".

A group of conference participants from Germany and Finland visited Agrisera's facility in Umeå during the evening of the second day of the event. 

Two Agrisera Best Poster Prizes, and a free antibody each from the Agrisera catalog, were awarded to:
  • Lenny Maliham-Yap from the Institute of Molecular Biotechnology, Graz University of Technology in Austria for the poster tilted "Probing the role of Ferredoxins in Cyanobacterial Biotransformations", and
  • Malene Olsen from the Department of Food Science, University of Copenhagen, Danmark, for the poster tilted "Breeding of Nannochloropsis oceanica for increaased growth rates using random mutagenesis".
Awaiting your free antibody choice!

The book "Photosynthesis, solar energy for life" was awarded to Shaikh Mohd Kashif from Univeirsity of Gothenburg as the first prize in a Quiz about proteins, plant science and antibodies, conducted by Agrisera. 

Thank you to all the conference participants for interesting discussions, suggestions and ideas!

Localization of plant clathrin using immunocytochemistry and Agrisera directly labelled anti-clathrin 1,2 antibodies

Material: Zea mays hybrid variety

5 days-old germinating maize root tips were cut and fixed with 4% formaldehyde, 60 min, RT. Cell walls were digested with enzymes cellulase and pectinase in MES buffer for 90 min, RT. After washing with PBS, roots were squashed gently using a flat tip forceps to release the cells into PBS buffer. Cells were allowed to settle O/N at 4°C, followed by immunolocalization.

Immunocytochemistry (ICC)
Cells were permeabilized with 0.5% Triton X-100, 10 min, RT, followed by washing with PBS buffer before blocking with 5% fish gelatin-PBS, 30 min, RT.

Detection antibody: Cells were incubated with rabbit anti-clathrin 1,2 primary antibodies conjugated with DyLight®594 (AS10 690-DL594, Agrisera) for 3h/RT. Nuclei were stained with DAPI followed Fluoromount-G mounting (Southern Biotech).

Immunofluorescent localization using Agrisera epitope tag antibodies

Take an advantage of Agrisera epitope tag antibodies in fluorescent immunolocalization of proteins under investigation

Immunofluorescent localization using Agrisera epitope tag antibodies
Various antibodies to epitope tags have been used for immunoifluorescent localization of target proteins in transfected HEK293 cells, including anti-HA (AS12 2220), anti-3xHis (AS20 4441) and anti-Myc (AS21 4529). Details of employed protocols are provided on the specific antibody product pages.

Agrisera Western blot workshop for Centre for Research in Agricultural Genomics (CRAG)

On the 12th of June Dr. Joanna Porankiewicz-Asplund, Agrisera's Technical Support Manager, conducted an online workshop for researchers from the Centre for Research in Agricultural Genomics (CRAG), Spain. 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. 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!
