Background of LASP1

LASP1 (LIM and SH3 domain protein 1), also known as LASP1, is a protein that in humans is encoded by the LASP1 gene. This gene encodes a member of a LIM protein subfamily which is characterized by a LIM motif and a domain of Src homology region 3. This protein functions as an actin-binding protein and possibly in cytoskeletal organization. LASP1 has been shown to interact with Zyxin. Tomasetto et al. (1995) mapped the LASP1 gene to chromosome 17q11-q21.3 by radioactive in situ hybridization. Northern blot analysis revealed that LASP1 mRNA was expressed at a basal level in all normal tissues examined and overexpressed in 8% of primary breast cancers. In most of these cancers, LASP1 and ERBB2 were simultaneously overexpressed.

We are currently using anti-LASP1 antibody PA1791-1 for human tissue, and we are happy with the WB results. The species of reactivity given in the datasheet says human. Is it true that the antibody can work on pig tissues as well?

Asked: 2017-06-30


The anti-LASP1 antibody (PA1791-1) has not been validated for cross reactivity specifically with pig tissues, though there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in pig you can get your next antibody for free. Please contact me if I can help you with anything.

Can you help my question with product PA1791-1, anti-LASP1 antibody. I was wondering if it would be possible to conjugate this antibody with biotin. I would need it to be without BSA or sodium azide. I am planning on using a buffer exchange of sodium azide with PBS only. Would there be problems for me to conjugate the antibody and store it in -20 degrees in small aliquots?

Asked: 2014-04-21


It is not recommended storing this antibody with PBS buffer only in -20 degrees. If you want to store it in -20 degrees it is best to add some cryoprotectant like glycerol. If you want carrier free PA1791-1 anti-LASP1 antibody, we can provide it to you in a special formula with trehalose and/or glycerol. These molecules will not interfere with conjugation chemistry and provide a good level of protection for the antibody from degradation. Please be sure to specify this in your purchase order.
