PVALB Polyclonal Antibody, Cat#CAC13889
Immunofluorescence staining of U251 cells with CAC13889 at 1:166, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
Western Blot, Positive WB detected in: Mouse brain tissue, Mouse kidney tissue, All lanes: PVALB antibody at 3ug/ml, Secondary, Goat polyclonal to rabbit IgG at 1/50000 dilution, Predicted band size: 13 kDa, Observed band size: 13 kDa
Immunofluorescent analysis of HepG2 cells using CAC13889 at dilution of 1:100 and Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L)

What our customers say

Custom Protein Expression Services

“We had concerns about hydrophobic proteins with poor solubility. Biomatik started from codon optimization and gene synthesis, and the resulting proteins had significantly improved solubility. In our ELISA assays, they showed high specificity and low background. Excellent quality, fast turnaround, and helpful support—highly recommended.”

— Dr. Jia, Centers for Disease Control and Prevention, Atlanta, GA, USA

Custom Antibody Production Services

“I work on molecular farming, producing recombinant protein in plant suspension cells. I'm completely satisfied after almost 5 years of ordering antibodies at Biomatik. Perfect reproducibility batch after batch, and I hope to continue like this!”

— Dr. Eduardo Peña, Ergo Bioscience Inc., Wilmington, DE, USA

Custom Antibody Production Services

“We are very satisfied with the peptide antibodies you produced. They work exceptionally well for both WB and immunostaining—strong and specific signals. Your pricing, service, and timelines are excellent. I will definitely continue using your service.”

— Dr. Han, Senior Research Associate, Department of Biology, McGill University, Montreal, QC, Canada

Custom Gene Synthesis Services

“Different groups here have found your service excellent. That’s why another group also decided to go with Biomatik—it came highly recommended.”

— Dr. Heilbronn, College of Life Sciences, University of Dundee, U.K.

Custom Antibody Production Services

We were very pleased with Biomatik’s performance on a custom recombinant protein project earlier this summer. Communication throughout the project was excellent, technical questions were addressed promptly, and the supporting analytical and QC data were clear and comprehensive. The recombinant protein was produced to the requested specifications and delivered on schedule. Based on this experience, we have chosen Biomatik for an additional custom protein production project and would be pleased to work with them again.
