Application

General Western Blot Protocol:
  • Glycoprotein sample size: 500ng
  • Lectin Concentration: 0.1ug/ml

  1. Load samples at 500 ng of glycoprotein per lane
  2. Run 4-20% Bis-Tris SDS page gel
  3. Transfer gel to a PVDF membrane
  4. Block membrane for 1 hr at RT with RIPA buffer (R0278 Sigma)
  5. Incubate HRP lectin at 0.1ug/ml with RIPA buffer for 2 hours at RT
  6. Wash membrane 5 x 5 minutes with 25ml RIPA buffer
  7. Detect using chemiluminescent substrate (CPS1-120)

Actions biochimiques/physiologiques

PNA does not agglutinate normal human erythrocytes, but strongly agglutinates neuraminidase treated erythrocytes. PNA has potent anti-T activity similar to the anti-T antibody in human sera. The lectin can be used to distinguish between human lymphocyte subsets.

Définition de l'unité

One unit will form 1 mg purpurogallin in 20 sec from pyrogallol at pH 6.0 at 20 °C.

Forme physique

Contains sodium citrate

Notes préparatoires

Prepared from peroxidase (P8375) using a modification of a published method, which favors low molecular weight conjugates. Repurified after conjugation by affinity chromatography.

Protein O-glycosylation has key roles in many biological processes, but the repertoire of O-glycans synthesized by cells is difficult to determine. Here we describe an approach termed Cellular O-Glycome Reporter/Amplification (CORA), a sensitive method used to amplify and profile mucin-type

A non-replicating form of pseudotyped influenza virus, inactivated by suppression of the haemagglutinin signal sequence (S-FLU), can act as a broadly protective vaccine. S-FLU can infect for a single round only, and induces heterotypic protection predominantly through activation of cross-reactive

Virus-like particle (VLP) technology is an alternative platform for developing vaccines to combat seasonal and pandemic influenza. Influenza VLPs are non-infectious nanoparticles that can elicit effective vaccine immunogenicity in hosts. B-cell-activating factor (BAFF, or BLyS) and a proliferation-inducing ligand (APRIL)

Dicer is a crucial enzyme for the maturation of miRNAs. Mutations in the Dicer gene are highly associated with Pleuro Pulmonary Blastoma-Family Dysplasia Syndrome (PPB-FDS, OMIM 601200), recently proposed to be renamed Dicer syndrome. Aside from the pulmonary phenotype (blastoma)

Ectothermal reptiles have internal pigmentation, which is not seen in endothermal birds and mammals. Here we show that the development of the dorsal neural tube-derived melanoblasts in turtle Trachemys scripta is regulated by similar mechanisms as in other amniotes, but
