Background of Maxi Potassium channel alpha

Calcium-activated potassium channel subunit alpha-1 also known as KCa1.1, or BK channel for short, is a voltage gated potassium channel encoded by the KCNMA1 gene and characterized by their large conductance of potassium ions (K+) through cell membranes. This gene is located on 10q22.3. BK channels are activated (opened) by changes in membrane electrical potential and/or by increases in concentration of intracellular calcium ion (Ca2+). It is essential for the regulation of several key physiological processes including smooth muscle tone and neuronal excitability. BK channels also contribute to the behavioral effects of ethanol in the worm C. elegans under high concentrations (> 100 mM, or approximately 0.50% BAC).It remains to be determined if BK channels contribute to intoxication in humans.

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.

5 Customer Q&As for Anti-Maxi Potassium channel alpha/KCNMA1 Antibody Picoband™


Will PB9227 anti-Maxi Potassium channel alpha/KCNMA1 antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

Verified Customer

Asked: 2020-01-13


You can see on the product datasheet, PB9227 anti-Maxi Potassium channel alpha/KCNMA1 antibody as been tested on IHC. 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.

We are currently using anti-Maxi Potassium channel alpha/KCNMA1 antibody PB9227 for human tissue, and we are well pleased with the IHC results. The species of reactivity given in the datasheet says human, mouse, rat. Is it possible that the antibody can work on primate tissues as well?

E. Yang

Verified customer

Asked: 2019-10-10


The anti-Maxi Potassium channel alpha/KCNMA1 antibody (PB9227) has not been tested for cross reactivity specifically with primate tissues, but 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 primate you can get your next antibody for free. Please contact me if I can help you with anything.

I have a question about product PB9227, anti-Maxi Potassium channel alpha/KCNMA1 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?

D. Wu

Verified customer

Asked: 2018-10-04


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 PB9227 anti-Maxi Potassium channel alpha/KCNMA1 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.
