Target

  • Relevance

    Retroviral vectors are commonly used for gene expression in vitro and in vivo. The structure of these vectors usually consists of one gene of interest and a selectable marker gene. Fast selection without damaging cells is a critical step for significant gene expression. Blasticidin S deaminase (Bsd) isolated from Bacillus cereus has a neutralizing action on the highly toxic antibiotic blasticidin. A variety of commercially available retroviral vectors, such lentiviral expression systems, utilize Bsd expression for selection using blasticidin. This selectable marker allows selection of stable mammalian cell lines in as little as one week.

  • Alternative names

    • Blasticidin-S deaminase antibody
    • BSD antibody

The cells were fixed in paraformaldehyde (3.75%) for 30 min., then permeabilized in 0.2% Triton X-100 for 15 min. Blocking was done using 1% BSA for 30 min. The primary was used at 1/100 and then an appropriate secondary antibody conjugated to Texas Red was used.

Answer

Thank you for contacting us. I am sorry to hear you have been experiencing problems with ab38307. The customer has made many changes to optimize and it is disappointing that the antibody is still not working. I would be happy to refund or replace the product. The only recommendation I would like to make is using 10% saponin for lysis, reviewing online protocols this is a common method to lyse Plasmodium falciparum and may be more effective than 1xPBS only. I hope this information helps. Looking forward to your reply on how to proceed.

Question

Could you tell me if the BSD antibody (ab38307) works on cells fixed with paraformaldehyde? Thank you very much in advance,

Read More
Answer

Thank you for your inquiry. The cells in the ICC/IF image for ab38307 were fixed in paraformaldehyde (3.75%) for 30 min., then permeabilized in 0.2% Triton X-100 for 15 min. Blocking was done using 1% BSA for 30 min, then the labeling was performed as described in the caption. I have updated our image caption with this information. Please contact us with any other questions.
