Applications

Our Abpromise guarantee covers the use of ab44392 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ELISA Use at an assay dependent concentration.
IHC-P 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
WB 1/1000. Predicted molecular weight: 71 kDa. 1/1000 when using colorimetric substrates such as BCIP/NBT, and 1/5000 for chemiluminescent substrates. EDTA/EGTA treatment of tissues or lysates is required to see latent zymogen. Dilution optimised using Chromogenic detection.

Target

  • Function
    The enzyme cleaves Lys-Arg and Arg-Ser bonds. It activates, in a reciprocal reaction, factor XII after its binding to a negatively charged surface. It also releases bradykinin from HMW kininogen and may also play a role in the renin-angiotensin system by converting prorenin into renin.
  • Involvement in disease
    Defects in KLKB1 are the cause of prekallikrein deficiency (PKK deficiency) [MIM:612423]; also known as Fletcher factor deficiency. This disorder is a blood coagulation defect.
  • Sequence similarities
    Belongs to the peptidase S1 family. Plasma kallikrein subfamily.
    Contains 4 apple domains.
    Contains 1 peptidase S1 domain.
  • Cellular localization
    Secreted.

Anti-Plasma Kallikrein 1B antibody images

  • ab44392 staining Kallikrein 1B in human temporal neocortical tissue sections IHC-P . Tissue samples were fixed with formaldehyde and blocked with 10% serum for 20 minutes at 23°C: antigen retrieval was performed by heat mediation in citrate buffer.. Samples were incubated with primary antibody (1/100) for 18 hours at 23°C . A biotin-conjugated horse anti Rabbit IgG  polyclonal (1/50) was used as secondary antibody.

This is frustrating for us too, finding incorrect information on our datasheets. We try to minimize it but there is clearly work to be done.

I did not realize you had already purchased the antibody. If you would still like to try it with rat...

My apologies: the laboratory that supplies this to us confirmed that they have not tested this for reactivity to rat protein, for have we or, to our knowledge, any of our customers. It is not clear why our datasheet lists rat in the "Reacts With" field...

Thank you for contacting us. Unfortunately, the immunogen sequence for that antibody is in fact proprietary, and we do not offer or accept confidentiality agreements, for this or other immunogen sequences.
