Background of CD19
B-lymphocyte antigen CD19, also known as CD19 (Cluster of Differentiation 19), is a protein that in humans is encoded by the CD19 gene. It is found on the surface of B-cells, a type of white blood cell. Lymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. The CD19 gene encodes a cell surface molecule that assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.
Antibody Validation
Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence, and ELISA with known positive control and negative samples to ensure specificity and high affinity, including thorough antibody incubations.

Figure 1. Western blot analysis of CD19 using anti-CD19 antibody (A00154-2).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 50ug of sample under reducing conditions.
Lane 1: rat spleen tissue lysates,
Lane 2: rat thymus tissue lysates,
Lane 3: mouse spleen tissue lysates,
Lane 4: mouse thymus tissue lysates,
Lane 5: human K562 whole cell lysates,
Lane 6: human 22RV1 whole cell lysates.
After Electrophoresis, proteins were transferred to a Nitrocellulose membrane at 150mA for 50-90 minutes. Blocked the membrane with 5% Non-fat Milk/ TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-CD19 antigen affinity purified polyclonal antibody (Catalog # A00154-2) at 0.5 μg/mL overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:10000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for CD19 at approximately 85KD. The expected band size for CD19 is at 61KD.

We have been able to see staining in human embryonic kidney. Any tips? Is anti-CD19 antibody supposed to stain embryonic kidney positively?
Verified Customer

Asked: 2020-04-09
Answer
From what I have seen in literature embryonic kidney does express CD19. From what I have seen in Uniprot.org, CD19 is expressed in spleen, tonsil, blood, b-cell, embryonic kidney, among other tissues. Regarding which tissues have CD19 expression, here are a few articles citing expression in various tissues:
B-cell, Pubmed ID: 15489334
Blood, Pubmed ID: 1370948
Embryonic kidney, Pubmed ID: 17525332
Spleen, Pubmed ID: 14702039

Question
Will A00154-2 anti-CD19 antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?
S. Krishna
Verified customer
Asked: 2017-04-10
Answer
It shows on the product datasheet, A00154-2 anti-CD19 antibody as been validated 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.

Question
I have a question about product A00154-2, anti-CD19 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?
N. Johnson
Verified customer
Asked: 2016-02-18
Answer
We suggest not 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 A00154-2 anti-CD19 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.
