Background of Caldesmon/CALD1

Caldesmon is a potential actomyosin regulatory protein found in smooth muscle and nonmuscle cells. The predicted smooth-muscle polypeptide is 793 amino acids long. The high molecular weight caldesmon (h-CaD) is predominantly expressed in smooth muscles, whereas the low molecular weight caldesmon (l-CaD) is widely distributed in nonmuscle tissues and cells. Hayashi et al. (1992) demonstrated that the human CDM gene is composed of 14 exons.

Antibody Validation

Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence and ELISA with known positive and negative samples to ensure specificity and high affinity.

6 Customer Q&As for Anti-Caldesmon (Smooth) Cald1 Antibody (Monoclonal, hHCD)


Would MA1009 anti-Caldesmon (Smooth) antibody (Monoclonal, hHCD) work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

Verified Customer

Asked: 2020-03-16


It shows on the product datasheet, MA1009 anti-Caldesmon (Smooth) antibody (Monoclonal, hHCD) as been tested on WB. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.

Would anti-Caldesmon (Smooth) antibody (Monoclonal, hHCD) MA1009 work on primate WB with skin?

Verified Customer

Verified customer

Asked: 2019-11-12


Our lab technicians have not tested anti-Caldesmon (Smooth) antibody (Monoclonal, hHCD) MA1009 on primate. You can run a BLAST between primate and the immunogen sequence of anti-Caldesmon (Smooth) antibody (Monoclonal, hHCD) MA1009 to see if they may cross-react. If the sequence homology is close, then you can perform a pilot test. Keep in mind that since we have not validated primate samples, this use of the antibody is not covered by our guarantee. However we have an innovator award program that if you test this antibody and show it works in primate skin in WB, you can get your next antibody for free.
